Current UHF CB Band Plan (80 Channels)

This is the current UHF frequency usage chart if you’re looking for a free channel or just don’t know what each channel is for. CB radios can be a lifesaver if the mobile and internet networks go down and are therefore an invaluable resource to preppers. On flat ground the signal can reach around 5kms (3.1 mi) using about 5 watts of transmitting power.

General chat channels are used in simplex mode, repeater channels must be used in duplex mode.
If you are not using a repeater, it is recommended to choose a “general chat” channel.
