Flange mount fixed antenna bracket. Investment cast 316 stainless steel construction. Designed to allow antenna wire to feed directly through the base eliminating the need for a separate cable grommet. Base is designed with a recess which, when filled with silicone sealant will form a watertight seal. Ideal for TV, Loran, GPS and VHF antennas as well as radar arches. For use with standard 1"-14 threads. Installs with three ź FH fasteners (not included).
