The Oricom ANU1100 All Terrain Antenna is our most popular innovation in the range of heavy duty and purpose built UHF CB Antennas. This super convenient pack includes a 3dBi short antenna including heavy duty large parallel spring base with elevated feed. The pack also includes a simple to install extension fibreglass whip to convert the 3dBi base to a 6.5dBi antenna. Essentially you have the best of two different gain options, in one convenient pack. Simply add the larger whip when you are travelling on flat, open terrain. Alternatively, take the whip off and the 3dBi is perfectly suited to hilly or more mountainous terrain.
