Der Icom AH-4 ist ein automatischer Langdraht-Antennentuner, der automatisch eine Drahtantenne mit einer Mindestlänge von 7 Metern im 3,5-54 MHz-Bereich an Ihren Transceiver anpasst.


Wide Tuning Range
The AH-4 provides reliable matching from 3.5 MHz to 54 MHz when using at least a 7 m (23 ft) antenna.

Automatic Digital Control Tuning
The built-in 8-bit microprocessor chooses the lowest SWR using 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. Once a frequency is memorized, the AH-4
tunes on that frequency in less than 1 second. Note that the AH-4 does not memorize a frequency which is normally tuned within 2.5 seconds. 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.

The AH-4 can be used with most of Icom HF transceivers, which covers HF through 50 MHz bands. However, the IC-706 and IC-736 can only be tuned in the 3.5–30 MHz range.
