High performance CB antenna kits complete with a 3 or 4 foot antenna, and a 3-way mounting bracket that will allow you to mount the antenna on a vertical or horizontal mirror arm or rail as well as directly to any flat vertical surface. The kits also includes our 18 foot Fire-Flex cable made from top grade RG-58A/U coaxial cable complete with two screw-on PL-259 connections. And, as a bonus for purchasing a complete kit, we throw in a FREE stainless steel spring and a FREE microphone hanger.And don"t forget ... ALL antennas, regardless of style or manufacturer, MUST be tuned after installation on the vehicle. Transmitting antennas are not "plug-n-play" devices
