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

Yes, some farm impliments that I blundered across in the 1970's.
1"-14 UNS (class 2a and 2b) are used only for marine mounts. UNS
means "Unified National Special" which makes it a defacto standard
thread.

What about 1" national fine thread hex bolt? Or 3/4" npt plumbing type
thread?

Did you perhaps notice that the 1"-14 UNS thread is a straight thread,
while all the NPT plumbing threads are tapered?

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.

I'll do everyone a favor and not describe some of the antenna mounting
abortions that I've seen in the Moss Landing and SCZ harbors, and at a
former employer in the marine biz. Let's just say that it can be made
to fit a variety of non-standard mounts, in a wide variety of ways,
most of really disgusting.

thnx for any advice,

So, what are you trying to accomplish?
