Detailed 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 reception from 4 to 30 MHz when the antenna is operated in a twin whip configuration, such as the OE-416A/SRC . It may be employed for general purpose broadband communications reception from VLF to 30 MHz, or general purpose tuned transmission from 4 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.
