mAT-40
HF-SSB Automatic Antenna Tuner
Instruction Manual Version V1.0
INTRODUCTION
The mAT-40 HF-SSB Automatic Antenna Tuner, lets you rapidly tune any antenna
automatically: unbalanced or single-wire. It can be operated by various brands of transmitters by
selecting different interface cables, such as ICOM, YAESU, and KENWOOD, just like their own
brand tuners. The tuner housing is produced by aluminum milling and oxidation surface
technology, beautiful, delicate, compact and firm. It can work well in all kinds of harsh outdoor
environments. The maximum size of the tuner is only 20 cm, which is the smallest outdoor
antenna tuner now.
The mAT-40 also features advanced memory tuning, providing 16000 memory locations. When
tuning near a previously used frequency it will recall the settings for nearly instant tuning. It learns
your favorite frequencies and bands as you use it. You can also start a tuning cycle manually
whenever necessary.
The tuner consists of the following parts: mAT-40 host, data cable (mAT-40-D, 10m), YAESU
interface cable (mAT-40-Y), ICOM interface cable (mAT-40-M), KENWOOD interface cable
(mAT-40-K), general interface cable (mAT-40-G). The mAT-40 host and mAT-40-D data cable
are necessary parts, and the rest of the interface cables are selected. You can choose different
interface cables according to your radio. The mAT-40-G universal interface cables are designed to
support other brands of radio besides YAESU, ICOM and KENWOOD. If your radio is of this
type, please choose this interface cable.
The mAT-40 has 16,000 frequency memories. When tuning on or near a previously tuned
frequency, the mAT-40 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-40 “learns” as it is used, adapting to the bands and frequencies as it goes.
