Unless the context otherwise requires, references in this prospectus to "ADDvantage," "we," "us," and "our" refers to ADDvantage Technologies Group, Inc. and its subsidiaries collectively. ADDvantage Technologies Group, Inc. Based in Broken Arrow, Oklahoma, we are a supplier of a comprehensive line of electronics and hardware for the cable television ("CATV") industry. Through our six wholly-owned operating subsidiaries, we distribute and service products used to acquire, distribute and protect the broad range of communications signals carried on fiber optic, coaxial cable and wireless distribution systems. Through our TULSAT subsidiary, we are an exclusive Scientific-Atlanta Master Distributor for certain legacy products and a distributor for most of Scientific-Atlanta's other products, including a nonexclusive distributor for select transmission and subscriber products sold in Argentina, Bahamas, Belize, Bolivia, Brazil, Caribbean Islands (excluding Cuba), Chile, Costa Rica, Colombia, Dominican Republic, Ecuador, El Salvador, French Guyana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Suriname, Uruguay and Venezuela. Our NCS subsidiary is one of two preferred distributors for Motorola's broadband products. Other subsidiaries distribute products for leading cable equipment original equipment manufacturers such as Standard, Corning-Gilbert, RL Drake Company, Blonder-Tongue Laboratories, Quintech Electronics, Videotek and others. Each of our subsidiaries also operates service repair centers specializing in Motorola, Magnavox, Scientific-Atlanta and Alpha Power Supplies repairs. We are known for carrying hard-to-find items and for our ability to respond quickly to customer needs. We sell new, used and refurbished products to customers that provide an array of communications services including television, high-speed data and telephony to single family homes, apartments and institutions such as hospitals, prisons, universities and schools. Some of our customers include large multiple system operations ("MSOs") such as Cablevision, Comcast, Cox and Time Warner; mid-market MSOs such as Cable One and Sequel III; competitive service providers such as Knology and Seren; and private cable companies such as those run by hotels, hospitals, schools and mobile parks.

The Offering Common Stock offered by selling shareholders...................500,000 shares Shares underlying stock options held by selling shareholders.3,000,000 shares Common Stock to be outstanding after the offering, based on shares outstanding on July 23, 2004................................10,081,789 shares American Stock Exchange symbol............................................AEY 3 No shares are being offered or sold by us either directly or through options or warrants. The options have been granted to Barron Partners, L.P. by David Chymiak and Kenneth Chymiak. Thus, neither the sale of any of the offered shares nor exercises of the options will result in an increase in the numbers of outstanding shares of our common stock. The total of 10,081,789 shares of common stock to be outstanding after this offering is based on the number of shares outstanding on July 23, 2004 as reported on our Form 10-Q for the period ended June 30, 2004. This is a continuous offering and is not underwritten. We cannot predict when or if the selling shareholders will sell their shares or exercise options entitling them to purchase and possibly sell shares underlying the options. This offering assumes that the selling shareholders will exercise all options they hold for purchase of our common stock, for cash and at the current exercise price. RISK FACTORS You should carefully consider the following risk factors, in addition to the other information set forth in this prospectus, before deciding to purchase any shares of our common stock. Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock. Additional risks not presently known, or which we currently consider immaterial also may adversely affect us. We are highly dependent upon our principal executive officers who also control us. David Chymiak, Chairman of the Board, and Kenneth Chymiak, President and Chief Executive Officer, currently own approximately 80% of our outstanding common stock and 100% of our outstanding preferred stock. Our performance is highly dependent upon the skill, experience and availability of these two persons. Should either of them become unavailable to us, our performance and results of operations would probably be adversely affected to a material extent. In addition, they will continue to own a controlling interest in us following this offering, thus restricting our ability to take any action without their approval or acquiescence. Likewise, as shareholders, they may elect to take certain actions which may be contrary to the interests of the other shareholders. Our business is dependent on customers' capital budgets. Our performance is impacted by our customers' capital spending for constructing, rebuilding, maintaining or upgrading broadband communications systems. Capital spending in the telecommunications industry is cyclical. A variety of factors will affect the amount of capital spending, and therefore, our sales and profits, including: * consolidations and recapitalizations in the cable television industry; * general economic conditions; * availability and cost of capital; * other demands and opportunities for capital; * regulations; * demands for network services; * competition and technology; and * real or perceived trends or uncertainties in these factors. Developments in the industry and in the capital markets in recent years have reduced access to funding for certain customers, causing delays in the timing and scale of deployments of our equipment, as well as the postponement or cancellation of certain projects by our customers. On the other hand, a significant increase in the capital budgets of our customers might actually impact us in a negative fashion. Much of our inventory consists of refurbished and surplus-new equipment and materials that we have acquired from other cable operators. If our customers seek higher end, more expensive equipment, the demand for our products may suffer. 4 The markets in which we operate are very competitive, and competitive pressures may adversely affect our results of operations. The markets for broadband communication equipment are extremely competitive and dynamic, requiring the companies that compete in these markets to react quickly and capitalize on change. This will require us to make quick decisions and deploy substantial resources in an effort to keep up with the ever-changing demands of the industry. We compete with national and inter- national manufacturers, distributors, resellers and wholesalers including many companies larger than we are. The rapid technological changes occurring in the broadband markets may lead to the entry of new competitors, including those with substantially greater resources than we have. Because the markets in which we compete are characterized by rapid growth and, in some cases, low barriers to entry, smaller niche market companies and start-up ventures also may become principal competitors in the future. Actions by existing competitors and the entry of new competitors may have an adverse effect on our sales and profitability. The broadband communications industry is further characterized by rapid technological change. In the future, technological advances could lead to the obsolescence of a substantial portion of our current inventory, which could have a material adverse effect on our business. Consolidations in the telecommunications industry could result in delays or reductions in purchases of products, which would have a material adverse effect on our business. The telecommunications industry has experienced the consolidation of many industry participants, and this trend is expected to continue. We and one or more of our competitors may each supply products to businesses that have merged, such as AT&T Broadband and Comcast, or will merge in the future. Consolidations could result in delays in purchasing decisions by the merged businesses, and we could play either a greater or lesser role in supplying the communications products to the merged entity. These purchasing decisions of the merged companies could have a material adverse effect on our business. Mergers among the supplier base also have increased, and this trend may continue. The larger combined companies with pooled capital resources may be able to provide solution alternatives with which we would be put at a disadvantage to compete. The larger breadth of product offerings by these consolidated suppliers could result in customers electing to trim their supplier base for the advantages of one-stop shopping solutions for all of their product needs. Consolidation of the supplier base could have a material adverse effect on our business. Our success depends in large part on our ability to attract and retain qualified personnel in all facets of our operations. Competition for qualified personnel is intense, and we may not be success- ful in attracting and retaining key executives, marketing, engineering and sales personnel, which could impact our ability to maintain and grow our operations. Our future success will depend, to a significant extent, on the ability of our management to operate effectively. The loss of services of any key personnel, the inability to attract and retain qualified personnel in the future or delays in hiring required personnel, particularly engineers and other technical professionals, could negatively affect our business. We are substantially dependent on certain manufacturers, and an inability to obtain adequate and timely delivery of products could adversely affect our business. We are a Value Added Reseller and Master Distributor for Scientific- Atlanta and a Value Added Reseller of Motorola broadband and transmission products. Should these relationships terminate or deteriorate, or should either manufacturer be unable or unwilling to deliver the products needed by us for our customers, our performance could be adversely impacted. An inability to obtain adequate deliveries or any other circumstance that would require us to seek alternative sources of supply could affect our ability to ship products on a timely basis. Any inability to reliably ship our products on time could damage relationships with current and prospective customers and harm our business. 5 We have a large investment in our inventory which could become obsolete or outdated. We have a large investment in inventory which could become obsolete or outdated. Much of our inventory is acquired from other cable operators and is in the nature of used, refurbished, remanufactured or surplus new equipment. Determining the amounts and types of inventory requires us to speculate to some degree as to what the future demands of our customers will be. If, because of technological changes, consolidation in the industry or competition from other types of broadcast media, the demands for our inventory could be reduced substantially, which would have a material adverse effect upon our business and financial results. Our outstanding common stock is very thinly traded. While we have approximately 10.1 million shares of common stock outstanding, 74.14% of these shares are beneficially owned by David Chymiak and Kenneth Chymiak and 4.96% are beneficially held by Barron Partners, L.P. As a consequence, only about 21% of our shares of common stock are held by nonaffiliated, public investors and available for public trading. The average daily trading volume of our common stock is low. As long as this situation exists, once the shares may be sold in the public market, it may be difficult for shares of our stock to be sold without materially affecting the demand and, consequently, the market price of our shares. Thus, investors in our common stock may encounter difficulty in liquidating their investment in a timely and efficient manner. We have not paid any dividends on our outstanding common stock and have no plans to pay dividends in the future. We have not paid any dividends on our common stock. We currently plan to retain our earnings and have no plans to pay dividends on our common stock in the future. We may also enter into credit agreements or other borrowing arrangements which may restrict our ability to declare dividends on our common stock. Our principal executive officers and shareholders have a number of conflicts of interest with us. Certain of our key properties are leased from entities owned by our principal executive officers. Also, these executives have made loans to us in various amounts in the past and are paid interest on these loans. These transactions are described in the proxy statement that is incorporated by reference into this prospectus. These arrangements create certain conflicts of interest between these executives and us that may not always be resolved in a manner most beneficial to us. Our international operations may be adversely affected by a number of factors. Although the majority of our business efforts are focused in the United States, we have international operations in the Philippines, Taiwan, Korea, Japan, Australia, Brazil, Ecuador, Dominican Republic, Honduras and a few Latin American countries. We currently have no binding agreements or commitments to make any material international investment. Our foreign operations may be adversely affected by a number of factors, including: * local political and economic developments could restrict or increase the cost of our foreign operations; * exchange controls and currency fluctuations; * tax increases and retroactive tax claims could increase costs of our foreign operations; * expropriation of our property could result in loss of revenue, property and equipment; * import and export regulations and other foreign laws or policies could result in loss of revenues; and * laws and policies of the United States affecting foreign trade, taxation and investment could restrict our ability to fund foreign operations or make foreign operations more costly. 6 FORWARD LOOKING STATEMENTS This prospectus and the documents we incorporate by reference include forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act.

USE OF PROCEEDS We will not receive any of the proceeds from the sale of shares of common stock offered by this prospectus. SELLING SECURITY HOLDERS Background On September 24, 2004, David E. Chymiak, our Chairman of the Board and owner of approximately 41.5% of our outstanding common stock and 50% of our outstanding preferred stock, and Kenneth A. Chymiak, our President and Chief Executive Officer and owner, together with his wife, of approximately 37.6% of our outstanding common stock and 50% of our outstanding preferred stock, entered into a stock purchase agreement with Barron Partners, L.P., a Delaware limited partnership whose main offices are in New York, New York, pursuant to which Barron Partners agreed to purchase from the Chymiaks 500,000 shares of our common stock at a price of $3.25 per share. These shares purchased by Barron Partners represent approximately 4.96% of our outstanding shares of common stock, based on the number of our outstanding shares at June 30, 2004. Bathgate Capital Partners, LLC received a fee of $97,500 in connection with the sale of the 500,000 shares and will receive additional fees if and to the extent that the options are exercised. Under the stock purchase agreement, Barron Partners was also granted three options to buy up to an additional 3,000,000 shares of common stock from the Chymiaks. The terms of these options are summarized as follows: Option No. of Shares Exercise Price Expiration Date No. 1 1,000,000 $4.25 15 months from date of prospectus 1 No. 2 1,000,000 $5.25 18 months from date of prospectus 1 No. 3 1,000,000 $6.25 24 months from date of prospectus 1 --------------------------- 1 The expiration date of each option shall be extended by the amount of time, if any, during which Barron Partners is restricted from selling any securities described in this prospectus due to the implementation of a "Black-out Period" by us pursuant to the stock purchase agreement. 7 Each option can be exercised at any time in whole or in part, except that each exercise must be for a minimum of 150,000 shares. The stock purchase agreement provides that the options are not exercisable to the extent that shares received upon exercise, when added to the shares that Barron Partners then beneficially owns, would represent more than 4.99% of our outstanding shares. This restriction can be eliminated by Barron Partners upon 61 days' prior written notice. The 3,500,000 shares covered by the stock purchase agreement represent approximately 34.7% of our outstanding shares of common stock. All of the shares which Barron Partners has the right to acquire under the terms of the stock purchase agreement, including the shares which they are entitled to receive upon exercise of the options, may be offered for sale from time to time by the selling shareholders pursuant to this prospectus. The term "selling shareholders" as used in this prospectus, includes Barron Partners, L.P. and their transferees, pledges, donees and other successors acquiring an interest in the shares after the date of this prospectus. The selling shareholders are not obligated to sell their shares. If they do sell their shares, they may be sold pursuant to this prospectus or in another permitted manner. Thus, no assurances can be given as to the number of shares that may be sold by the selling shareholders or that will be held by them upon completion of the sales. Information concerning the selling share- holders may change from time to time and the changed information will be presented in a supplement to this prospectus if and when necessary and required. We do not know whether or when the options will be exercised or how long the selling shareholders may hold their shares before selling them. We currently have no agreements, arrangements or understandings with any of the selling shareholders regarding sales of their shares. Barron Partners, L.P. has not had a material relationship with us or any of our subsidiaries within the past three years. They also have sole voting and investment power with respect to the shares they acquire pursuant to the stock purchase agreement. PLAN OF DISTRIBUTION We are registering the offer and sale of the shares covered by this prospectus on behalf of the selling shareholders. As used in this prospectus, the term "selling shareholders" includes donees, pledgees, transferees or other successors-in-interest selling shares received from a selling shareholder after the date of this prospectus. The selling shareholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. The selling shareholders may sell their shares from time to time in one or more types of transactions (which may include block transactions) on the American Stock Exchange, in the over-the-counter market, in negotiated transactions, through put or call options transactions relating to the shares, through short sales of shares, or a combination of these methods of sale, at market prices prevailing at the time of sale, at negotiated prices, or at varying prices determined at the time of sale. These transactions may or may not involve brokers or dealers. The selling shareholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares, nor is there an underwriter or coordinating broker acting in connection with the proposed sale of shares by the selling shareholders. The selling shareholders may sell their shares directly to purchasers or to or through broker-dealers, which may act as agents or principals. These broker-dealers may receive compensation in the form of discounts, concessions, or commissions from the selling shareholders and/or the purchasers of shares for whom these broker-dealers may act as agents or to whom they sell as principal, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions). The selling shareholders also may resell any of their shares that qualify for sale under Rule 144 in open market transactions pursuant to Rule 144 under the Securities Act, rather than pursuant to this prospectus. 8 The selling shareholders and any broker-dealers that act in connection with the sale of their shares might be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act, and any commissions received by these broker-dealers and any profit on the resale of the shares sold by them while acting as principals might be deemed to be underwriting discounts or commissions under the Securities Act. We have agreed to indemnify the selling shareholders against certain liabilities, including liabilities arising under the Securities Act. The selling shareholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of their shares against certain liabilities, including liabilities arising under the Securities Act. Because the selling shareholders may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act, the selling shareholders will be subject to the prospectus delivery requirements of the Securities Act. We have informed the selling shareholders that the anti-manipulative provisions of Regulation M promulgated under the Exchange Act may apply to their sales in the market. Upon notification to us by a selling shareholder that any material arrangement has been entered into with a broker-dealer for the sale of shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing: * the name of the selling shareholder and of the participating broker-dealer(s); * the number of shares involved; * the price at which the shares were sold; * the commissions paid or discounts or concessions allowed to the broker-dealer(s), where applicable; * that the broker-ealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus; and * any other facts material to the transaction. We will pay all the costs, expenses and fees related to the registration of the shares offered by this prospectus. The selling shareholders will be responsible for the payment of any brokerage commissions, underwriting fees or discounts or fees or expenses of counsel or advisors attributable to the sale of the shares.

Indemnification of Directors and Officers. The registrant's Certificate of Incorporation, as amended ("Certificate of Incorporation") and Bylaws provide that each person who was or is made a party to, or is involved in, any action, suit or proceeding by reason of the fact that he or she was a director, officer, employee or agent of the registrant (or was serving at the request of the registrant as a director, officer, employee or agent for another entity) will be indemnified and held harmless by the registrant, to the fullest extent not prohibited by the laws of Oklahoma. Under Section 1031 of the Oklahoma General Corporation Act (the "OGCA"), a corporation may indemnify a director, officer, employee or agent of the corporation against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of an action brought by or in the right of a corporation, the corporation may indemnify a director, officer, employee or agent of the corporation against expenses (including attorneys' fees) actually and reasonably incurred by him or her if he or she acted in good faith and in a manner he or she reasonably believed to be in the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless a court finds that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper. The OGCA permits Oklahoma corporations to include in their certificates of incorporation a provision eliminating or limiting director liability for monetary damages arising from breaches of their fiduciary duty. The Certificate of Incorporation provides that to the maximum extent permitted by law, a director of the registrant shall not be liable to the registrant or its shareholders for monetary damages for breach of fiduciary duty as a director. The only limitations imposed under the OGCA and the Certificate of Incorporation are that a director's liability will not be limited: (i) for breaches of the director's duty of loyalty to the corporation or its shareholders, (ii) for acts or omissions not in good faith or involving intentional misconduct or known violations or law, (iii) for the payment of unlawful dividends or unlawful stock purchases or redemptions, or (iv) for transactions in which the director derived an improper personal benefit. II-1 The foregoing summaries are necessarily subject to the complete text of the statutes, the Certificate of Incorporation and Bylaws referred to above and are qualified in their entirety by reference thereto. Item 16. Exhibits. The following exhibits are filed herewith unless otherwise indicated: 1.1 Form of Underwriting Agreement (any underwriting agreement entered into with respect to any of the shares offered hereby will be filed as an exhibit to a current report on Form 8-K and will be deemed incorporated herein by reference). 5.1 Legal Opinion of Conner & Winters, P.C (filed herewith). 23.1 Consent of Conner & Winters, P.C., is contained in its opinion included as exhibit 5.1. 23.2 Consent of Tullius Taylor Sartain & Sartain LLP (filed herewith). 24.1 Power of Attorney (appears on the signature page of this registration statement). ----------------- Item 17. Undertakings. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement to: (i) include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and (iii) include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. II-2 (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933, may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions discussed in Item 15 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Tulsa, State of Oklahoma, on October 28, 2004.
