Please note that the mAT-CI (Icom) control cable and the mAT-CK (Kenwood) control cable are both optional.

• mAT-CK, control cable Kenwood (product code 700723)
• mAT-CI, control cable Icom (product code 700724)

The mAT-180H provides automatic antenna tuning across the entire HF spectrum, 1.6 - 54 MHz, plus 6 meters, at power levels up to 120 watts. It will tune dipoles, verticals, yagis, or virtually any coax-fed antenna. It will match an amazing range of antennas and impedances, far greater than some other tuners you may have considered, including the built-in tuners on many radios.

The mAT-180H is an automatic antenna tuner specially designed for modern Icom and Kenwood HF transceivers. With matching control cables, tuners can be used for corresponding transceivers.

For Icom transceivers you need the optional mAT-CI control cable. Icom transceivers that can work with the original AH-3 and AH-4 automatic tuners of Icom can also work with the mAT-180H. Which includes the IC-706, 703, 718, 7000, 7100, 7200, 7300, 7410, 746, 756, 7600 series and other Icom transceivers.

Kenwood transceivers need the optional mAT-CK control cable. Kenwood transceivers that can work with the original AT-250, AT-300 tuners can use the mAT-180H, which includes TRC-80, TK-80, TS-2000, 50, 450, 480SAT (excluding HX version), 570, 590, 850, 870, 990 and so on. The Kenwood TS-430 / TS-440 are too old to use this tuner.

The mAT-180H has 16,000 frequency memories. When tuning on or near a previously tuned frequency, the mAT-180H uses "Memory Tune" to recall the previous tuning parameters in a fraction of a second. If no memorized settings are available, the tuner runs a full tuning cycle, storing the parameters for memory recall on subsequent tuning cycles on that frequency. In this manner, the mAT-180H "learns" as it is used, adapting to the bands and frequencies as it goes.

There are four fine-tuning buttons on the front panel of the mAT-180H, and sometimes you can get a lower SWR with them. It also has a "TUNE" button on the front panel, which can also start tuning.

To facilitate the use of wire antennas, in addition to having two SO-239 standard RF sockets, the rear panel of the mAT-180H has two terminals, one red and one black. Red terminal for connecting the wire antenna, black terminal for connecting the ground wire. The mAT-180H connects to the transceiver via its tuner jack to control the tuning cycle, the transceivers tune button controls the tuner. The tuner jack also powers the tuner, so it requires no external power supply.

Please note: The mAT-180H is rated at 120 Watts maximum power input at most. Many HAM transceivers, and virtually all amplifiers, output well over 120 Watts. Power levels that significantly exceed the given specifications will definitely damage or destroy your mAT-180H. If your tuner fails during overload, it could also damage your transceiver. Be sure to observe the specified power limitations.
