Astron Wireless Technologies, Inc. offers a series of
aluminum yagis for VHF through 900MHZ voice and data applications. They range
from 2 element antennas with 4dBd of gain to 15 element yagis with more than
13dBd of gain. They incorporate Astron’s exclusive "Eversealed" feed
system which was developed to provide long term protection from exposure in
the most extreme environments. This feed system is fully balanced which will
provide a clean, symmetrical radiation pattern. The standard yagis are built
using a ¾" thick square aluminum boom which provides optimal structural
integrity. The Astron yagi is also easy to install with the solid aluminum
mounting blocks and stainless steel hardware provided. In addition, a flexible
pigtail cable is also provided to mate with heavier feedlines, eliminating
cable stresses and the need for jumper cables. Astron also manufactures a heavy
duty version of this antenna with a thicker, 1" square aluminum boom.
These antennas are an excellent choice for survivability in repeated installations
or for extreme environments where continual access is limited.
