18-Ft Aluminum Whip Antenna AS-3773B/U
Frequency Range: 10 MHz to 30 MHz
Power Handling: 5000 W Average
The AS-3773B/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, such as the OE-418A(V)1/SRC . 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.
