MAT-TUNER
Automatic Tuner For Icom & Kenwood Transceivers

INTRODUCTION

The mAT-180H is an automatic antenna tuner designed for modern Icom and Kenwood HF
transceivers. It has two control cables, mAT-CI (Icom) and mAT-CK (Kenwood).
The mAT-180H is supplied standard with the mAT-CI (Icom) cable. The mAT-CK
(Kenwood) cable is sold as an accessory.
When mAT-180H is used with Icom transceivers vai the supplied mAT-CI control cable, it is
fully compatible with the original AH-3 and AH-4 automatic tuner protocol. Transceivers that
can use either AH-3 or AH-4 tuners include IC-706, 703, 718, 7000, 7100, 7200, 7300, 7410, 746,
756, 7600, 7610 series transceivers.
When the tuner is used with Kenwood transceivers via the mAT-CK control cable, it is
compatible with the Kenwood AT-300 tuner protocol. Kenwood transceivers that can use
mAT-180H are TS-2000, 50, 450, 480SAT (excluding HX version), 570, 590, 850, 870, 990, etc.
In addition to controlling the mAT-180H tuning operation, the transceiver also supplies power
to the tuner through the control cable. Tuners do not need external power. Like the original tuner
the operation of mAT-180H is simple. After setting transceiver menu, tuning operation can be
completed by pressing the tuning button on the front panel of the transceiver.
The mAT-180H has a matching range of 1.8-54 MHz, at power levels up to 120 watts. It will
tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. Impedance matching range 5-
1500 ohms, in excess of the internal automatic antenna tuner or other external automatic antenna
tuners available.
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. You
can also start a tuning cycle manually whenever necessary.

AN IMPORTANT WORD ABOUT POWER LEVELS
The mAT-180H is rated at 120 watts maximum power input at most. Many ham transmitters
and transceivers, and virtually all amplifiers, output well over 120 watts. Power levels that
significantly exceed specifications will definitely damage or destroy your mAT-180H. If your
tuner fails during overload, it could also damage your transmitter or transceiver. Be sure to
observe the specified power limitations.
