ICOM AH-730 Brochure
AH-730
AUTOMATIC ANTENNA TUNER
Fast Tune-up from 1.8 to 50 MHz Band
Remote Control with Icom Transceivers
Wide Frequency Coverage
With a 7 m (23 ft) or longer wire element, all band matching is
possible from the 1.8 MHz (160 m) band to the 50 MHz (6 m)
band. Efficient for multi-band operation.
* A ground connection is required.
High Speed Tuning IPX4 Water Resistant
The automatic tuning operation can be made at a high speed
of about 2 to 3 seconds. It has 45 memories to store the
minimum SWR settings. When re-tuning the same frequency,
matching can be achieved in about 1 second.
Minimum RF Output for Tuning
The AH-730 emits only 0.3 W of RF output from the antenna
during tuning operation. The low power minimizes the risk of
interference to other stations while matching the antenna.
The tuner case uses a high-strength resin which protects
internal parts from water, weather, and salt damage. The
tuner is tested to IPX4 water splash protection. In addition,
the coaxial cable and control cable can be easily connected
without opening the case.
