Description
The AS-3771B/U 14 foot aluminium
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 4 to 30 MHz when the
antenna is operated with a suitable tuning system. It may be employed
for general purpose broadband communications reception from VLF to 30
MHz.
The antenna consists of a
tapered aluminium 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. |
