ICOM AH-4 Automatic Antenna Tuner

The Icom AH-4 coupler covers all amateur bands from 3.5 MHz through 50 MHz with a 7 (23 ft) or longer wire antenna, or the optional AH-2b antenna.

Compact yet durable, it's designed for easy installation in a variety of locations, outdoors, on a back porch or in your vehicle. Weather-resistant construction, using rubber gasket seals, enables operation in all conditions.

The AH-4 is designed for use with Icom HF transceivers. Just push [TUNER] switch on most modern Icom transceivers and the AH-4 adjusts imediately to the minimum SWR. The AH-4 automatically performs tuning operations for mode, power settings, etc. The average tune-up time is less than 2.5 sec. on each band.
