HF + 50MHz Automatic Antenna Tuner

Information

-WIDE TUNING RANGE The AH-4 provides reliable matching of frequencies from 3.5 MHz to 54 MHz when using at least a 7 m (23 ft) antenna; or 7 MHz to 54 MHz when using the AH-2b Antenna ELEMENT. - AUTOMATIC DIGITAL CONTROL TUNING The built-in 8-bit microprocessor chooses the lowest SWR condition from more than 1,040,000 different LC (coil/capacitor) combinations. - 45 FREQUENCY MEMORIES FOR FAST TUNING The LC combinations of 45 previously-used frequencies are automatically memorized in the AH-4. Once a frequency is memorized, the AH-4 tunes on that frequency in less than 1 sec. Note that the AH-4 does not memorize a frequency which is normally tuned within 2.5 sec. Memories are retained only when the power is on. - WEATHERPROOF DESIGN The AH-4’s tightly sealed plastic case allows convenient mounting virtually anywhere. The AH-4 can be mounted outdoors under your Antenna. - 0.3 W RADIATED POWER Radiated power during tuning is less than 0.3 W, minimizing interference to other stations. NOTE: 50 MHz tuning is possible with the IC-729*, IC-706MKII, IC-746 and IC-756; the IC-706 and IC-736 can only be tuned 3.5-30 MHz. * Connect a 50 MHz Antenna connector for 50 MHz operation.
