The AS-3770B/U 18 foot
aluminum whip transmitting/receiving antenna is designed and built
to meet the US Navy requirements for shipboard antennas. The antenna
Meets MIL-S-901 grade A for shock; MIL-STD-167 for vibration.
The antenna is used with
general HF communications equipment. The antenna provides vertically
polarized, omni-directional azimuth radiation from 10 to 30 MHz when
the antenna is operated in a twin whip and tuner configuration for
broadband applications. It can be used singularly for general
receiving or transmitting applications.
The antenna consists of a
tapered aluminum radiating element and an integral fibreglass
insulator and base mounting flange. It is a single piece antenna
which has three side feed points. The integral insulator and base
mounting flange is bonded to the bottom of the radiating element. A
drip shield is provided just below the lower feed point.
The mechanical strength of the
integral insulator and mounting flange is achieved with a patented
process using high strength filament fibreglass and epoxy resin.
