Contact friends or neighbors —
find out “what’s happening” or
plan a get-together.
Ever have car trouble or run out
of gas on the highway? What an
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.
