Description
The AS-4366A/U is a general purpose
VHF broadband communications antenna system. Ideal for
shipboard applications, this antenna system is a base mounted
version of the AS-3900A/VRC,
featuring rugged construction and rigid mounting of the whip
section.
The AS-4366A/U antenna system provides
omni-directional,
vertically polarized coverage over the 30 to 88 MHz frequency
range. It is conservatively rated for 150 Watts of RF input
power and exhibits a VSWR of less than 3.5:1 over the entire
operating band with reference to a 50 Ohm line impedance.
The Input RF connection is made through a single coaxial N-Type
connector located centrally on the bottom of the mounting base.
The mounting base houses the matching unit and electro-magnetic
pulse (EMP) protection.
A two-piece, permanently joined fibreglass whip element and a
polycarbonate mounting base with a rigid antenna support make up
the antenna system's simple two-piece construction. It is
approximately 110 inches in height, has an antenna element
diameter of less than 1 inch and weighs about 11 pounds.
The antenna system has been designed to meet the vibration and
service requirements of MIL-S-901, Type A and MIL-STD-810.
Mounting is provided by four 0.453 inch diameter holes (for 3/8 hardware) on a 4.5 inch diameter bolt circle located on the
mounting flange at the base of the antenna system. |
