Information
                                    •WIDE TUNING RANGE
The AH-3 provides reliable matching for frequencies from
3.5 MHz to 30 MHz when using at least a 3 m (10 ft) antenna
such as the AH-2b ANTENNA ELEMENT (with a 50 cm lead-in wire).

When operating above 1.8 MHz, use at least a 12 m (40 ft)
antenna.

•AUTOMATIC DIGITAL CONTROL TUNING
The built-in 8-bit microcomputer chooses the lowest SWR
condition from more than 260,000 different LC
(coil/capacitor) combinations.

•EIGHT-FREQUENCY MEMORY FOR FAST TUNING
The LC combinations of 8 previously used frequencies are
automatically memorized in the AH-3. Once a frequency is
memorized, the AH-3 tunes on that frequency in less than 1
sec. Note that the AH-3 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-3's tightly sealed plastic case allows convenient
mounting virtually anywhere. The AH-3 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.
