Maintain a clear line of communication by adding the Browning BR-140 CB Land Mobile Antenna to your radio set-up. It has a 49" stainless steel, allowing you to catch signals over a wide area. This indoor mobile antenna works on frequency waves between 26 and 30MHz, giving you more communication options. It also has a premium-quality solid brass chromed base for added stability and improved sound quality and uses a DC ground shunt fed base load. This safely manages the electrical current. The device is compatible with NMO mounting (available separately) and attaches easily with a threaded connection. There is also the option to attach the antenna to a magnetic mount. With 3dB of gain, speech comes through clearly through radio speakers.
