Item #1014 ICOM AH-4 Automatic Antenna Tuner - $275 or best reasonable offer
-
WIDE TUNNING 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 7MHz to 54 MHz when using the AH-2b ANTENNA ELEMENT.
-
AUTOMATIC DIGITAL CONTROL TUNNING
The built-in 8-bit microprocessor chooses the lowest SWR conditiion from more than 1,040,000 different LC (coil/capacitor) combinations.
-
45 FREQUENCY MEMORIES FOR FAST TUNING
The LC conbinations 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 mountain 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.
