Hand-held CB.

There are special CBs for use on foot, usually referred to as "Walkie Talkies" or "Hand Held". These are self contained units with the CB, antenna and batteries all in the one unit.

Although some hand-held CB radios are lower power, most will transmit around the same power as any other legal CB and will have a receiver that is as sensitive. The main factor which will limit the range of one of these radios is likely to be the antenna. You cannot hope to get the same range with a built in antenna as you would on a good mobile or base one. When a Hand Held CB is plugged into a mobile or base antenna, it will perform as well as any other legal CB would on that antenna.

Some hand-helds are designed for less than 40 channels. The hand-held shown above, a Sonic 10-4 Envoy, has only two channels and much less power than a standard radio.

Some radios are designed to be adaptable for use in a car, at home, or as a portable radio. Although these will have built in batteries, antenna and microphone, they will also have sockets available to allow external power, antenna and microphones to be used. Such radios are extremely adaptable, allowing you to take the radio from the car and walk around with it or even use it at home with a large antenna.
