assurance it is to be able to radio for assistance!

Camping, fishing, and other sports are more fun with a CB. Locate a buddy or find out “what’s cooking” back at camp.

CB Courtesy

Wait for a pause in someone else’s transmission before you ask for a break.

If you do not receive an answer to your call after a second attempt, sign off and wait sev- eral minutes before trying again.

Do not hold down the micro- phone talk button when you are not talking. (This is called dead keying.)

Assist callers with directions, information about road condi- tions, and any other reasonable requests.

Maximum Range

The maximum range and quality of CB transmissions vary depending on these conditions:

The type and quality of antenna used.

The height of the antenna’s mounting location the higher the antenna, the better the sig- nal’s range.

The surrounding terrain mountains and tall buildings limit the range.

Weather conditions.

The number of nearby CBs operating on the same channel.

Standing wave ratio (SWR) between the antenna and the CB. You can check the SWR between the CB and a mobile or base-station antenna using an SWR tester (Cat. No. 21-523). Follow the instructions supplied with the SWR tester and the mobile or base-station antenna to change the SWR, if neces- sary.
