Instruction Manual
FRONT PANEL
On the front panel there are two LED indicator lights.
ONLINE: tuner’s status, online or bypass.
POWER: the tuner’s power light.
REAR PANEL
The rear panel of the mAT-K100 features four connectors.
ANTENNA
: SO-239 connector for coax cable from antenna.
RF IN:
Connect a 50 ohm coax jumper cable from this standard SO-239 connector to the ANT
jack on the back of the transceiver.
Radio:
This 4-pin mini-DIN connector is connected to the tuner control socket of the transceiver
through a matching control cable. DC power is also supplied over this jack.
GND:
Connect to antenna system ground.
CONTROL CABLE
Control cables are used to transmit control commands between transceivers and tuners.
Standard length is 50 centimeters. If it is desired that the mAT-K100 is positioned farther from
the transceiver than this cable length allows, a custom cable will need to be constructed. This can
be accomplished in two ways: Cut the supplied cable and solder a jumper wire between all the
connections, or purchase new connectors and cable to construct a custom-length interface cable
from scratch.
The socket used to connect the control cable on the tuner is shown below.
