Mat-Tuner mAT-50 Instruction Manual

INTRODUCTION

mAT-50 is the latest long-wire antenna tuner we have designed. It uses a number of advanced
control technology, is currently the highest level of control technology antenna tuner. It is
specially designed to tune long-wire antennas.
mAT-50 consists of two parts: tuner and coupler. Tuner are outdoor parts for tuning antennas.
The coupler is an indoor part which is used to connect the transceiver, provide power for the tuner
and control the tuner for tuning. There is only one 50 ohm RF coaxial cable between the tuner and
the coupler.
There are two versions of the coupler, the YAESU version and the ICOM&KENWOOD version,
which are used to connect YAESU and ICOM&KENWOOD transceivers, respectively. In the
future, we will also design a third version of the coupler - Universal coupler, which will be
applicable to all brands of radio, not just the three brands of radio. The coupler is optional, you
can choose the suitable coupler according to your transceiver. You can buy the coupler separately
later.
mAT-50 uses "No-Control-Line" technology and "Power-Off-Hold" technology. No-Control
-Line technology can transmit RF power signal, control signaling and DC power on coaxial cable.
The tuner does not need to be connected to a control line alone, making the tuner easy to install
and use. Power-Off-Hold technology is that the tuner is powered only in tuning, and the coupler
interrupts the tuner's DC after tuning. Since the tuner uses a magnetic latching relay, it can still
maintain its current state after power failure. This technology enables mAT-50 to have more stable
performance and excellent anti-interference capability. At the end of tuning, the tuner is not
powered, completely avoiding the stray radiation produced by the CPU oscillation circuit of the
tuner affecting the receiving effect of the transceiver.
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-50 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.
