Hi

Does the Shakespear or standard marine antenna base that is 1" 14tpi fit
anything else?

What about 1" national fine thread hex bolt? Or 3/4" npt plumbing type
thread? Anyone have any luck using something else without ruining the
threads? I cannot use one of their oem swivel base things for the
application I thinking of doing.

thnx for any advice,

The thread is Straight Cut as opposed to NPT, which is Tapered...
HOWEVER,

I have cut 3/4" NPT Threads, using my Pipe Threader, that will work on
Marine Antennas. The trick is to have an Adjustable Die, and cut the
threads just a tad bit deeper than normal 3/4" NPT. It works well, as
long as your Pipe has enough wall thickness, to take the deeper
threading. I have used in in Alaska for years, and had no issues with
the antennas or mounts.
