Antenna Downlink, Inc. (ADL) established in 1979 by Gerry and Virginia Blachley, to develop, test and manufacture antenna and feed systems. The company builds a complete line of C-band (both linear and circular polarized), Ku-Band, and S-Band feeds, as well as a line of adjustable scalar feeds. ADL has been granted four U.S. Patents and has additional pending patent applications in the U.S., Canada, Japan, and Europe.

In February of 2002, Patriot Antenna Systems purchased the Internationally known feed company.

New technologies must be utilized in today’s competitive market. ADL’s® decision not to build a scalar feed as the first product line, was based on the fact that the choke plate (scalar) feed design was old technology.

Extraordinary progress has been made in feed design since the 1960s by the aerospace industry. One design was of particular interest, a dual mode “SMART-FEED.” The advantages were tremendous, “terrestrial interference rejection,” carrier to noise ratios and “side lobe performance were major improvements” due to controlled “Dual Moding.”

The natural way to plot an intelligent growth of a Company is to include all products that relate to its industry. In 1993 and after 10 years, A.D.L.® added the RP3 series Scalar feed to the product line, with resounding applause and acceptance.
