Radio Shack 21-1679 A ユーザーズマニュアル

To install the supplied antenna, align 

the two slots on the antenna connector 

with the tabs on the BNC connector 

of the CB radio. Push the antenna 

connector to the CB radio and rotate 

the antenna connector clockwise until it 

locks into place.

The CB’s BNC connector allows you to use a variety of optional 

antennas, including external mobile antennas and outdoor base 

station antennas.
Always use the 50-ohm, RG-58, or RG-8 coaxial cable to connect 

an outdoor antenna. If the antenna is over 50 feet from the CB 

radio, use the RG-8 low-loss dielectric coaxial cable.
Safety Precaution:
If an outside antenna is installed, be sure the antenna system is 

grounded so as to provide protection against voltage surges and 

built-up static charges. When installing the antenna, be careful not 

to touch overhead power lines as contact with them might be fatal.

Connect an external speaker (not 

included) to the SPK jack of your 

CB radio. This mutes the CB’s 

internal speaker.
Connect an external microphone 

(not included) to the MIC jack of 

your CB radio. This disables the 

CB’s internal microphone.
