Download Manual



The 29 LTD Classic has been the standard of excellence in professional CB radios for over 50 years. Now you can get the classic CB with new dual-mode AM/FM so you'll have clearer sound with less background noise. Cobra 29 LTD CB radios are known for their performance, reliability, and durability and will provide you with years of reliable service. Now, thanks to Cobra's leadership to enable FM mode usage with CBs used in the United States, you can enjoy dual-mode AM/FM functionality in your CB.

 Internally, the 29 LTD is based on the classic 29 LTD but with new FM electronics.
  Like previous Cobra 29 LTD, the new 29LTD includes 4 Watts AM RF power output, the maximum allowed by law, instant access to emergency channel 9 and information channel 19, as well as Delta Tune to clarify incoming signals and adjustable Dynamike® boost, which increases the microphone’s sensitivity for increased voice clarity.

The item most overlooked when ordering a custom radio is the microphone.  Your new radio will NOT sound great with a stock mic on it even if you have it tuned.  If your CB is more than a tool for work, you NEED to upgrade your microphone. 
My personal favorites are the
Astatic 636L and RD104E.
