Add this cool option to your Antenna Kit and have the ability to remove your antenna quickly and easily. No tools are required! Just press down against the spring and give a half-twist and the antenna comes off easily. This option allows you to keep your CB antenna in your Truck or at home for those trips where you do not need it. It keeps your antenna from being stolen if/when you park in areas that can't be trusted or if you park in structures where your antenna height could be a problem.
