Cobra Electronics has set the standard for reliable driver communication solutions with more than 40 years of producing dependable, top quality CB radios. In 2008, Cobra introduced the world’s first-ever CB radio with Bluetooth® wireless technology, providing drivers a new means to communicate safely and easily on the road.
CB (Citizens Band) radio is simply a 2-way voice communication system that lets you talk to other CB users. It lets you talk from your truck, car, home, business, or boat to any other CB operator on the same channel. Technically, it is a transceiver. It functions both as a radio transmitter (when sending messages) and a receiver (when receiving messages). Citizens Band Radio was created by the Federal Communication Commission (FCC) in 1958. In that year the FCC authorized 23 channels for private citizen use. CBâ€™s popularity soon congested these channels, so the FCC added 17 more channels for a total of 40, effective January 1, 1977.
How far can I talk on a CB?
How far you can communicate depends on a number of things: natural obstructions such as hills and valleys; radio interference and atmospheric conditions; man-made obstructions like bridges and tall buildings. Normally, communications are limited between five and seven miles depending on the above conditions.
