Thank you for purchasing the Cobra 29 LTD AM/FM Pro Series CB Radio Transceiver. Properly used, this Cobra product will give you many years of reliable service.
Citizens Band Radio
History Invented by Al Gross in 1945, the CB radio originally served as a method of communication for troops during World War II. After the war, Gross worked to make two-way radios a way of communication for personal use and the CB radio service was established by law in the U.S. in 1949. It wasn’t until the 1970s that technology advanced and the CB market caught on as a method of communication between drivers to report police speed traps and road hazards. The Citizens Band Radio Service consists of 40 channel frequencies that are mostly 10 kHz apart.
Transmitter power is limited to 4 watts in the US, and range can vary depending on the terrain and quality of the product. Currently, the Citizens Band service does not require a license for operation, regardless of age, as long as the rules of operation established by the Federal Communication Commission (FCC) are followed.
Petition For FCC
Part 65 Rule Changes In 2016, Cobra petitioned the FCC to revise Part 95 rules to allow CB radios to use frequency modulation (FM). Cobra contended that FM offers improved speech quality and lower noise interference, which improves the standard of two-way radios and is a benefit to the customer. Through the direct efforts of Cobra Electronics and the enthusiastic support from loyal customers and the distribution network the FCC granted the request. In 2021, Part 95 officially was updated to include FM as an option for two-way radio use. Today, thanks to Cobra Electronics’ petitions to improve the quality of the Citizens Band Radio Service, users can enjoy the benefits of CB radio communication in a range of industries.

Installation
Location
Plan for the location of the CB transceiver and microphone bracket before starting the installation. Select a location that is convenient for operation, yet does not interfere with the driver or passenger.
The transceiver is usually mounted to the underside of the dash with the microphone bracket beside it.
NOTE: The transceiver is held in the universal mounting bracket by two thumbscrews which allow for adjustment to a convenient angle. The bracket includes two self-tapping screws and star washers. The mounting must be mechanically strong and conveniently located.
Antennas
CB Antenna
Since the maximum allowable power output of the transmitter is limited by the FCC, the antenna is critical in affecting transmission distance. Only a properly matched antenna system will allow maximum power output. Cobra loaded type antenna models are highly recommended for most installations. Consult your Cobra dealer for further details, or call 800-543-1608 and speak to a Cobra representative. A standard antenna connector is provided on the transceiver for easy connection.
Cobra offers CB antenna and mounting solutions that can be purchased online.
