The K-Tek Shark (L) Antenna Mount is made from a single piece of 3" anodized aluminum tubing with a mounting bracket that allows the antenna mount to sit nicely over a sound cart. Both Sharks come with (2) mounting rings that are movable anywhere along the aluminum tube. These mounting rings have two 3/8"-16 threaded studs for mounting antennas.
Additional Mounting Rings are available. KTEK AMR
