     Broken Arrow, Oklahoma, June 15, 2005--ADDvantage Technologies Group, Inc.
(AMEX:AEY), today announced that its subsidiary, Tulsat, a Master Stocking
Distributor of Scientific-Atlanta current and legacy equipment, has exclusive
distribution rights for select Scientific-Atlanta products.  Scientific-
Atlanta has appointed Tulsat as an exclusive distributor of its System
Amplifier III RF platform (excluding accessories) for United States customers.
Based on the maturity of the System Amplifier III product line, Tulsat will
provide its customers the expertise necessary to maintain a superior level of
customer support and responsiveness.

     "Tulsat's large inventory of System III amplifiers, line extenders and
accessories will allow the Company to fill the majority of our customers'
orders from our inventory, thus eliminating a lengthy lead time in obtaining
the required products to complete system extensions or new construction,"
commented David Chymiak, Chairman of the Board of ADDvantage.

     "Our sales early in the third fiscal quarter have increased over second
quarter levels," added Ken Chymiak, President and CEO.  "Although there is
continued slowness in some product categories, we expect this product expansion
will complement the trend seen so far this quarter."
