Detailed Description

The AS-1735/SRC, UHF Antenna is a rugged, vertically polarized, broadband antenna covering the frequency range of 225 MHz to 400 MHz. This light weight antenna has an all aluminum outer structure which can be mounted around an existing mast ranging from 4 inches to 12 inches in diameter.

​

As an option, the AS-1735/SRC can also be made to mount onto masts of up to 15 inches in diameter. Contact Valcom for ordering details.

​

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

​

The four radiating elements are fed in-phase from a single input and provide omni-directional radiation in the azimuth plane.

​

The AS-1735/SRC antenna can be used in either the transmit mode or the receive mode without any adjustments. It can handle a peak envelope power (PEP) of 2 KW and exhibits a nominal input impedance of 50 ohms and a VSWR of less than 1.8:1 over the entire frequency range of 225 MHz to 400 MHz.

​

The antenna has been designed to meet the vibration requirements of MIL-STD-167, TYPE I and II, the shock requirements of MIL-S-901 and the environmental requirements of MIL-E-16400H.
