INSTALLATION
The Z-817H 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 Z-817H 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.
