APPLICATION INFORMATION

Mobile Operation

The Z-100Plus is perfectly suited to mobile operation. It can be installed under the dashboard
along with the transceiver, or mounted remotely. The only requirement is that the tuner remains
dry.
The optional radio interface cable is 14 inches long. If it is desired that the Z-100Plus 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 optional 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 connectors are standard 1/8" stereo plugs, available from
most electronic supply catalogs, such as Mouser Electronics. The female jack is Mouser part
number 16PJ106-EX, and the male plug is Mouser part number 17PP004-EX.

a good SWR match was found.
Tuning cycle is complete;
tuning match is between 1.5 and 3.0 SWR.
Tuning cycle is complete;
tuning match is greater than 3.0:1 SWR.
Tuning cycle failed, RF was lost in the
middle of the tune.
