Ok, I will try this from a different angle.

1" - 14TPI UNS thread like you described are very rare outside
of the large machine industry.  They are used for things
like bolts on tractors.  I have a pretty big doubt that it
has any application in a GPS antenna.

US pipe thread in the sizes 1/2", 3/4", and 1" are 14TPI, they
are not "1.0 inch" in any dimension, however.

It is pretty common to use standard pipe fittings in antenna
work.

So how did you arrive at needing a 1"-14TPI UNS die?

Hi Dave,

Check with your local "plumbing"-store. In Sweden the "old inch based pipe
thread" lives on, slightly renamed. Se attached .jpg for approximate
inside/outside diameters.

The pipes are sold in 6m lenghts threaded in both ends.

Good luck in your search!

the specification for the thread from.

Pipe has O.D. of 1".

This is the standard Marine antenna mount I believe.

I think it is also known as 3/4" NPT for a pipe with a nominal OD of 1.05"

Hi Dave,

That would 3/4 inch NPT (National Pipe Thread).  In the UK it is known
as "Gas Pipe".  As far as I can tell, it is standard the world over.

There are some differences, that won't matter in your application.  In
Europe, NPT is frequently not tapered.  This is apparently the result of
not understanding that tapered pipe thread is self sealing.  As a result,
there have been all sorts of o-ring jamb nuts and other insane stuff done
"over there" to try and form a temporary seal... but I digress.

Chuck,

In France, Gas Pipe threads are tappered. However, I do not remember if they
follow the Metric or British standard for size...
