Detailed Description
The
AS-4163/URC
dual UHF channel antenna is a rugged, self supporting vertically
polarized broadband antenna covering the frequency range of 225 to
400 MHz. This light weight purpose antenna can be used in the
transmit or receive mode.
The antenna is
designed for use under severe environmental conditions encountered
abroad shipboard.
The two independent
radiating elements are housed in a single fibreglass radome
with an internal fibreglass mounting base. A
feed-through cable runs from the base to the top aluminium flange of the antenna
so that another antenna type can be mounted on the top flange.
The two antenna
channels are high power, balanced dipoles each capable of handling
power levels of up to 1 KW average. The isolation between
the two channels is excess of 25 dB. Each channel input VSWR
on the 50 ohm impedance is less than 3.0:1with average VSWR 2.5:1
over the entire 225 to 400 MHz frequency range.
The antenna has been
designed to meet the vibration requirements of MIL-STD-167, type I
and II, shock requirements of MIL-S-901, and the environmental
requirements of MIL-E-16400H.
