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. regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
