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

•The type and quality of antenna used

•The height of the antenna’s mounting location — the higher the antenna, the better the signal’s range

•The surrounding terrain — mountains and tall buildings limit the range

•Weather conditions

•The number of nearby radios operating on the same channel

•Standing wave ratio (SWR) between the antenna and the CB.
