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, all purpose antenna can be used in the transmit or receive mode.

​

The antenna is designed for use under severe environmental conditions encountered in a shipboard environment.

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 aluminum 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 more than 25 dB. Each input channel's VSWR is less than 3.0:1 with an average VSWR of 2.5:1 over the entire 225 to 400 MHz frequency range.

​

The antenna has been designed and tested 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.
