Installation - LDG KT-100 Operation Manual

INSTALLATION

The KT-100 tuner is designed for indoor operation only; it is not water resistant. If you use it
outdoors (Field Day, for example), you must protect it from the rain. The KT-100 is designed for
use with coax-fed antennas. If use with longwires or ladder-line-fed antennas is desired, an
external balun is required. The LDG RBA-4:1 or RBA-1:1 is ideal, depending on the antenna
and transmission line used.
Always turn your radio off before plugging or unplugging anything. The radio may be
damaged if cables are connected or disconnected while the power is on.
Connect the HF antenna jack on the transceiver to the TX jack on the back of the KT-100,
using a 50 ohm coax cable rated 125 watts or greater. On the TS-480 and TS-2000 radios, the
KT-100 must be connected to the ANT 1 jack of the transceiver. The TS-480 and TS-2000 will
not initiate an external tuning cycle if ANT 2 is selected.
instead, on those models equipped with an internal tuner, such as the TS-480SAT and TS-2000.
On models without an internal tuner, pressing AT while ANT 2 is selected will have no effect.
Connect the supplied radio interface cable to the mini-DIN 7-pin jack on the rear of the KT-
100, marked "Radio". Connect the other end of this cable to the six-pin AT-300 interface port on
the rear of the transceiver. That connector looks like this:
The internal tuner will be used,
