The Uniden PRO501TK Portable Handheld CB Radio includes the CB features you need every day. 40 CB channels let you tune in to the action channels or break away to do your own thing. The PRO501TK comes complete with a high-gain magnetic mount antenna. This will greatly increase the transmit and receive range by simply placing the antenna outside your vehicle. The ultra-strong magnet will hold it firmly in place. NOAA Weather keeps you informed when severe weather threatens. And the Dual Watch feature lets you talk on 1 channel while keeping an ear on another channel you are interested in. The PRO501TK 40-channel CB radio can be used with the included flexible rubber antenna and rechargeable or alkaline batteries for portable use. Remember, Uniden is the name in CB radios!
