Mounting and compatibility
Choose a compatible 3/8-inch x 24 antenna stud mount with sufficient support and an adequate ground plane. Confirm the mounting thread, vehicle clearances, and installation requirements before ordering. Matching threads alone do not establish suitability for every mount or vehicle.
This listing is for the 3-foot white AUT300-W, not the other sizes or colors in the AUT series. A mounting spring is optional. The existing product guidance recommends an SS3M medium spring for 2- to 3-foot AUT antennas; a spring is not listed as included.
SWR tuning and setup
Check and tune the antenna after installation with an appropriate SWR meter, following the antenna manufacturer's instructions. Adjust the tunable tip for an acceptable SWR across the CB channels you intend to use. Do not assume the antenna is already tuned for your particular installation.
Select coax and mounting hardware that meet your setup's requirements, and route the cable without sharp bends, crushing, or unnecessary strain. The stated 1,000-watt rating is an antenna power-handling rating, not added transmitter output or a guarantee of communication range.
