The mount is intended for applications where the coaxial cable is protected inside the mount with direct feed through the deck. Some antenna's allow for the cable coming out the side at the top of the steel mount, but it is preferred to bring the cable down the centre if possible, as the signal cable can get chaffed over time against the top of the tube.

This product fits all products with an internal 1”-14 TPI threads.
