IC AH-730 Automatic Antenna Tuner |
Specifications
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
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.
IPX4 Water Resistant
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.

IC AH-4 Automatic Antenna Tuner |
The
ICOM AH-4 automatic antenna tuner is designed to work with select ICOM
transceivers including the Icom 703, 706 series, 746 series, 756 series and
others.
It provides reliable matching of frequencies from 3.5 to 54 MHz when using a
wire of at least 23 feet (7 m) in length. It can also be used for matching 7 to
54 MHz when used with a 9 foot stainless steeel whip in a mobile situation. The
built-in 8-bit microprocessor chooses the lower SWR condition from more than
1,040,000 different LC (coil/capacitance) combinations. The LC combinations of
45 previously-used frequencies are automatically memorized by the AH-4. Once a
frequency is memorized, the AH-4 tunes on that frequency is less than one second.
(Memories are retained only when the power is on).
The AH-4 is sealed in a plastic weatherproof case for convenient mounting
outdoors under your antenna. The transceiver and the AH-4 tuner must have a
proper ground connection. Use a short heavy gauge wire or strap for this. This
tuner may be attached to a pole using the two supplied U Bolts, or to a flat
surface (screws and bolts are supplied).
The AH-4 comes with a 16 foot (5 m) control cable that connects to the rear
panel of compatible ICOM transceiver. A 16 foot (5 m) raw coax cable and two
PL-259s are supplied to connect the transceivers antenna output to the AH-4
antenna input. The PL-259s must be soldered on by the user.
This tuner requires about 10 watts (5-15 Watts) to activate and can handle up
to 120 watts. It operates on 13.8 VDC (less than 2 amps) drawn from the
transceiver control cable.
Size: 7x2.9x9.2 inches 2.65 Lbs. (172x70x230mm 1.2 kg).
Cable
set to connect AH-4 tuner to all recent ICOM HF radios.

IC AT-140 Automatic Antenna Tuner |
The
AT 140 matches any frequency on every HF marine band. For example, the tuner
matches a 7 m; 23 ft long-wire antenna across 1.6-30 MHz. Full automatic tuning
Just push the [TUNE] switch on the transceiver, and the AT 140 adjusts
immediately to the minimum SWR of any frequency on any HF marine band.
HF operation on any size ship
The AT 140 allows you HF operation where antenna element length is restricted
due to space.
Weather resistant The AT 140 is housed in a durable, completely weather
resistant ASA case with a rubber gasket.
45 memories for shorter tuning time
To decrease the tune-up time, the AT-140 automatically stores the matching
conditions for up to 45 frequencies. Re-tuning for a memorized frequency takes
approx. 1 second. Super capacitor for memory backup Even if the AT-1 40 is not
used for approx. 1 week, the built-in super capacitor backs up contents of the
45 memories.
Low power tune up
The AT-140 emits low output power during tuning. This feature reduces the
possibility of causing interference to other stations.
Tuner through function
The tuner through function is built into the AT-140. This function helps
improve receiver gain, depending on the antenna element length used, and
operating frequency.

IC AT-141 Automatic Antenna Tuner |
Automatic
HF Radio Tuner For use with Icom IC-M802 MF/HF SSB marine radio
Matches all bands: The AT-141 matches any frequency on every HF marine
band. For example, the tuner matches a 7 m long-wire antenna across 1.6–30 MHz.
Full automatic tuning Just push the [TUNE] switch on the transceiver, and the
AT-141 adjusts immediately to the minimum SWR of any frequency on any HF marine
band.
HF operation on any size ship The AT-141 allows you HF
operation where antenna element length is restricted due to
space.
Weather resistant The AT-141 is housed in a durable,
completely weather resistant ASA case with a rubber basket. The
antenna tuner can be conveniently installed both on the deck or
in the cabin near the antenna element.
Simple installation Installation is simple. Just connect the
control and antenna cables. You never need to open the cover.
45 memories for shorter tuning time To decrease the tune-up
time, the AT-141 automatically stores the matching conditions
for up to 45 frequencies.
Re-tuning for a memorized frequency takes approx. 1sec.
Super capacitor for memory backup even if the AT-141 is not
used for approx. 1 week, the built-in super capacitor backs up
contents of the 45 memories.
