Overview
The PMX-ANT is a universal AM/FM/WB amplified antenna built for Rockford Fosgate PMX source units and other 12-volt radios that need more signal in remote areas. Powered, it adds up to 20 dB of gain; unpowered it passes signal at 0 dB. Double-sided tape mounting, a quick power connector, and generous cable lengths simplify installs on boats, UTVs, and motorcycles.
Product details
Stronger radio signal where coverage is thin
Trail and water radios often struggle far from transmitters. The PMX-ANT is Rockford Fosgate’s amplified AM/FM/weather-band antenna for PMX head units and similar 12-volt systems. When powered from 9–16 VDC it provides up to 20 dB of signal boost; unpowered it passes RF at 0 dB so you are not stuck if the power lead is unused.

Tape-mount install, short idle draw
The compact housing measures about 0.96 × 1.11 × 3.89 inches and mounts with double-sided tape. A quick power connector speeds the 12-volt hookup, and idle current stays under 20 mA. Antenna cable is 8.4 feet (256 cm); the power lead is 3.58 feet (109 cm). Operating temperature is rated from −30°F to 70°F. Pair it with a PMX radio when you need clearer AM, FM, or weather-band reception away from town.
