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 Icom, Kenwood, and Yaesu
transceivers by selecting different interface cable adapters. The tuner housing for permanent
outdoor use is produced by aluminum milling and oxidation surface technology, It can work well
in all kinds of harsh outdoor environments.
The tuner consists of the mAT-40 host and control cable (mAT-40-D, 10 meters length). One
interface cable adapter for YAESU (mAT-40-Y), ICOM (mAT-40-M), and KENWOOD (mAT-40-
K) are required for connection between the control cable and the transceiver.
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.
