PREPARATION

ATTACHING THE

ANTENNA

The supplied magnet-mount antenna is designed for use only in emergen- cy or low speed, short-driving situa- tions. If you want to use the CB while driving your vehicle at highway speeds, on long-distance trips, or during periods of high, gusty winds or heavy turbulence, you need an op- tional standard-mount antenna (available at your local RadioShack store). If you use a standard-mount antenna, you also need a plug adapt- er (Cat. No. 278-208) to connect the standard antenna’s PL-259 plug to ANT on your CB.

Follow these steps to mount the sup- plied antenna.

1.Hold the antenna in an upright position and extend the antenna.

Note: Fully extend the antenna for maximum range.

2.While your vehicle is stopped, place the base as near as possi- ble to the center of your vehi- cle’s highest flat surface with pointing toward the front of your vehicle. (Do not remove the me-

tallic backing on the bottom of the magnetic base.)

Notes:

The base should have full sur- face contact with steel for the best possible range.

To reduce wind force, place the base toward the back win- dow.

3.Plug the magnetic base’s wire into the CB’s ANT jack.
