Using the HTX-242 as a Base Station

Although we designed the HTX-242 primarily for use as a mobile transceiver, you can also use it as a base station. To do so, you need these items:

•13.8-Volt DC regulated power supply that can supply at least 10 amps continuous power

•Base station antenna

•50-ohm coaxial antenna cable and connectors

Follow these steps to connect the HTX-242 as a base station.

1.Mount the base station antenna according to its instruc- tions.

Warning: For your safety, follow all cautions and warnings included with the base station antenna.

2.Connect the antenna cable to the antenna jack on the back of the HTX-242.

3.Connect the black power wire to the power supply’s negative

(–) terminal.

4.Connect the red power wire to the power supply’s positive (+) terminal.

5.Connect the power supply to a source of power.
