INSTALLATION
The YT-450 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 YT-450 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.
Compatible Transceivers
The YT-450 is designed to be used
ONLY
with the following Yaesu 100 watt transceivers:
FT-450
FT-950
WARNING:
Do not attempt to use the YT-450 with any other transceivers, even if the CAT
plug fits. At best, the YT-450 simply won’t work with these radios. At worst, it could cause
damage to the YT-450, the radio, or both.
It is possible that more Yaesu transceivers will be added to this list as Yaesu releases new
models. Be sure to check the LDG website for additional information.
Interface Cable
The YT-450 is supplied with a radio interface cable. Each end has two connectors. The end
with an 8-pin mini-DIN connector goes to the radio, and the other end goes to the tuner. Control
data is carried over the DB-9 connections; 12V power is tapped from the 8-pin mini-DIN, and is
delivered to the tuner via the round DC coax plug.
