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.
