SCHEDULE 13D/A

Explanatory Note

This Amendment No. 3 to Schedule 13D amends and supplements the Schedule 13D filed on February 15, 2007, as amended by Amendment No. 1 filed on February 18, 2009, and by Amendment No. 2 filed on February 22, 2012 by the Reporting Person, and is being filed to report the cumulative effect, as of August 26, 2016, of vesting by the Reporting Person of Shares (as defined below) and to provide an update relating to the Reporting Person’s investment in the Issuer.

This statement relates to shares of common stock, par value $.01 per share (the “Shares”), of TESSCO Technologies, Incorporated (the “Issuer”), 11126 McCormick Road, Hunt Valley, Maryland 21031.  All Share figures in this statement have been adjusted to reflect the Issuer’s stock dividends over the years.

(a)           The name of the Reporting Person is Robert B. Barnhill, Jr. (the “Reporting Person”).

(b)           The Reporting Person’s business address is 11126 McCormick Road, Hunt Valley, Maryland 21031.

(c)           The Reporting Person is Chairman, President and Chief Executive Officer of the Issuer.

(d)           No.

(e)           No.

(f)            The Reporting Person is a citizen of the United States of America.

The disclosure regarding the CEO Succession (as defined in Item 4) in Item 4 is incorporated herein by reference.

The Reporting Person may acquire additional Shares through the vesting of performance share units granted to him in his capacity as an executive officer of the Issuer.

The Shares covered by this statement were acquired by the Reporting Person by: purchases directly from the Issuer prior to the Issuer’s 1994 initial public offering; the past exercise of stock options granted by the Issuer under stock option plans maintained by the Issuer; the issuance by the Issuer to the Reporting Person of restricted Shares and performance stock units

under award plans maintained by the Issuer; and the issuance by the Issuer to the Reporting Person of stock dividends on issued and outstanding Shares.

The Reporting Person has acquired the Shares covered by this statement from time to time to increase his equity position in the Issuer and to compensate the Reporting Person for his services to the Issuer.

As disclosed in the Issuer’s Form 8-K filed on March 31, 2016 and in the Issuer’s earning release issued on May 9, 2016, the Issuer has launched a Chief Executive Officer succession plan and expects to hire a new Chief Executive Officer during its 2017 fiscal year.  Once the Issuer hires a new Chief Executive Officer, the Reporting Person will no longer serve as President and Chief Executive Officer of the Issuer and will become Executive Chairman of the Issuer.  Additionally, after the Reporting Person has transitioned his responsibilities as President and Chief Executive Officer, he will become senior advisor to the new Chief Executive Officer and to the Issuer’s Board of Directors (the “Board”).  The events discussed in this paragraph are referred to as the “CEO Succession.”

The Reporting Person intends to review his investment in the Issuer on a continuing basis.  Depending on various factors, including but not limited to the Issuer’s financial position and strategic direction, price levels of Shares, conditions in the securities markets, and general economic and industry conditions, the Reporting Person, during and after the CEO Succession, may take actions with respect to his investment in the Issuer.  These actions include changing his current investment purpose and/or, from time to time, (i) acquiring or causing affiliates to acquire additional Shares or other securities of the Issuer (collectively, “Securities”) in open market transactions, in privately negotiated transactions or through other methods; (ii) disposing or causing affiliates to dispose of some or all of the Securities in open market transactions, in privately negotiated transactions or through other methods; or (iii) continuing to hold or causing affiliates to hold the Securities (or any combination or derivative thereof).  In addition, during and after the CEO Succession, the Reporting Person may engage in discussions with members of the Board, the Issuer’s management, the Issuer’s other stockholders, potential investors in the Issuer and/or other parties regarding, or take actions concerning, the Issuer’s business, operations, governance, management, strategy and/or capitalization.  These discussions and/or actions may also relate to, or may result in, any matter set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D.

The information set forth in rows 7 through 13 of the cover page to this Schedule 13D is incorporated by reference.  The percentage set forth in row 13 is based on 8,309,241 outstanding Shares as of July 29, 2016, as reported in the Issuer’s Form 10-Q filed on August 4, 2016.
