ICOM
AH-4
AUTOMATIC
ANTENNA TUNER
Suitable
for all HF Icom transceivers -
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 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 - For
