I have  the same problem with several GPS antennas, a Quadrifilar from 
Raytheon,  
Irvine 2640NW with mounting base, HP 58532A with mounting base, 
HP  58504Ac. etc. Some complete boxes from HP do contain an adapter.
So this  thread is definitively a kind of standard. The thread is fully
cylindrical,  all the plumbers tubes do use conical threads which are not 
compatible.  Very difficult to find proper solution in the metrical Europe.
If I would  find a source of that HP-adapters I would buy 4 units.
I did not check for  the correct naming of this thread though.


---------------
As commented previously, this is a common fitting and fairly standard  for 
GPS antennas and some other antenna kit, especially in a marine  environment.
 
A variety of adaptors is available from marine suppliers ranging from  
expensive stainless steel fittings to much cheaper plastic, they are also  
regularly listed on Ebay.
 
However, there doesn't seem to be anything readilly available  which has a 
collar to sit over a plain pipe, which I suspect might  meet David's needs.
They are widely available with a flange fitting, for mounting to flat  
surfaces, or rail fittings to attach to horizontal deck rails, but perhaps a  
trawl through some of the marine suppliers might throw up something else that  
could do the job without the need for threading the end of the pipe.
