It is designed to easily handle 200 W of RF input power with a VSWR of under 2:1. The AS-390/SRC is comprised of a small cylindrical stub radiator and an eight bar-whip ground plane. It is designed to withstand the harsh environmental conditions unique to seagoing vessels.
ASSEMBLY INSTRUCTIONS No Assembly Required. INSTALLATION INSTRUCTIONS As shipped, the AS-390 antenna is designed to mount atop the Valcom AS-4163/URC antenna via the optional mount. The antenna simply threads into the mount until firmly snug. OPERATING INSTRUCTIONS Connect a suitable RF coaxial cable (such as RG-142) from the vehicle’s radio setup to the bottom of the antenna.
