MAXIMUM RANGE

The maximum range and quality of CB transmissions
vary depending on the following typical conditions:

• the type and quality of antenna used

• the height of the antenna's mounting location —

the higher the antenna, the greater the signal's
range

• the surrounding terrain — mountains and tall

buildings limit the range

• weather conditions

• the number of nearby CBs operating on the

same channel
