Established in 1979 to develop, test and manufacture
antenna and feed systems. In 1982, we decided to concentrate on only one
type of product...Antenna Feeds. We use a dual Hybrid moding feed as our
primary design because of its superior carrier to noise ratio performance and
terrestrial interference rejection. The company builds a complete line of
C-band (both linear and circular polarized), Ku-Band, and S-Bands, as well as a
line of adjustable scalar feeds. A.D.L. has been granted 4 U.S. Patents
and has additional pending patent applications in the U.S., Canada, Japan, and
Europe.FULL CATALOG AVAILABLE UPON REQUEST
New technologies must be utilized in today's competitive market. A.D.L.'s®
decision not to build a scalar feed as our first product line, was based on the
fact that the choke plate (scalar) feed design was old technology. In 1979
the TVRO industry was looking for an inexpensive antenna feed; what happened
then, is what happens all too often: an old idea is dusted off,
"renamed," and low and behold we have a new product, "the scalar
feed;" or do we? The history books say our "new friend,"
the scalar feed, is nothing more than an "alias" for the choke plate
feed design, that had been used in the 1950s, and 1960s with varying degrees of
success. The design has been shown to be defenseless to terrestrial
interference ("TI"), and cannot take advantage of controlled moding,
thereby limiting its performance.
Extraordinary progress has been made in feed design
since the 1960s by the aerospace industry. One design was of particular
interest, a dual moding "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 "SMART-FEED" now named
the RP1 Dual Hybrid had been tested.
In 1986 the TVRO Industry had to have a co-borsight
feed. It was an awkward time for A.D.L.® as the capital was not there to
hire a Research and Development team to design the new feed; what was there, was
the desire and determination. In February 1987, the Satellite Industry saw
the first true non compromised high performance CKU Centerline® feed that was
not only superior in performance, but was reasonably priced.
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.
