Shakespeare flange mounts can be used to attach marine VHF antennas to deck or bulkhead.  The mounts do not adjust for slanted surfaces, and do not allow lowering the antenna  for fishing, passage under overhangs, or for boat storage or towing.  These Shakespeare mounts are usually used for small VHF antennas, GPS and radar devices, and marine TV antennas atop radar arches and the like.
