-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
- 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.
