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.

Picking a CB Radio
It's important to understand that all CB radios are limited to 4 watts of output power. And because all CB radios have the same output, spending more on a radio won't provide an edge in terms of power or transmission range. A radio's features are what set it apart and are the primary differentiator when considering which radio is right for you. When it comes to range, it's the antenna that determines how far you can transmit and receive.
CB radios have numerous available features. Some of the most popular are weather channels for real-time weather updates, backlit displays for easy night use, public address mode for use with a PA horn, and noise-reduction filters for improved clarity.
So, how do you decide which radio is right for you? As the output power is the same for all models, you should focus on which features are most important for your needs. If you drive frequently at night, you'll want to consider a radio with a backlit display. If you travel often in the winter, a radio with weather channels will likely prove useful. You'll also want to consider the radio's size. If you have a large truck or semi, you likely have ample room to mount a full-sized CB radio. However, if you'll be installing the radio in a Jeep with less cab room, a small compact unit will be a much better choice.
