VHF/UHF LINE OF SIGHT
COMMUNICATION ANTENNAS
SINGLE OR MULTIPLE
COLINEAR DIPOLES
Antenna Design and Manufacturing
Corporation’s VHF/UHF LINE OF SIGHT COMMUNICATION ANTENNAS are broadband
dipoles designed for ground-air-ground, air traffic control and base
communication applications in the VHF frequency ranges from 30 to 90 MHz
and 118 to 1741 MHz, VHF/UHF frequency range from 400 to 1000 MHz. The
broadband single or multiple collinear dipole is linearly polarized and
produces omni-directional radiation pattern, with a nominal gain of 0
dBi minimum over the frequency range of operation. The dipole antenna is
capable of handling 200 Watts of CW power and has SWR of 2.5:1.0 over
the frequency range.
The construction of the antenna is
such as to render it capable of with standing the rigors of ships,
vehicle top mounting and tactical transportable usage in the most
hostile environments like wind loading with ice, temperature extremes,
vibration and shock. The radiating elements of the dipole are treated
for corrosion resistance and are protected from weather by a fiberglass
radome housing. The antenna is fit for use in marine and other
atmosphere.
Also available are phased arrays of
2 or 4 dipoles in an assembly for 3 or 6 dB additional gain.
