PL259 Thread standard
Thanks Dan,
I have ordered a die nut to correct the problem, I suspect that the thread will not have the full strength after using it though! Thanks, John "Dan Richardson" wrote in message ...

Yeah I know!) it was advertised as a PL259/SO239 male/female thread to enable a groundplane to be fitted to a mobile antenna. I assumed wrongly that there was an International standard with regard to the PL259/SO239. Naturally when a known part number is advertised, one would expect that the normal 5/8" x 24 threads per inch standard (UNEF) would be followed. Not so! What was sent was a 16 x 1mm adaptor. Naturally the language difference is making it hard for me to convince the seller that he MUST advertise the adaptor on Ebay having a metric thread. Can anyone tell me if there is a move towards the metrification of the PL259/SO239 connectors? If this happens all hell will break loose, imagine trying to connect antenna to coax at say a field day or even worse in an emergency situation? John VK2KCE I ran into that problem many years ago when they first starting importing some off-shore VHF antennas. I ended up purchasing a 5/8-24 NF die-nut and that took care of the problem. Its very easy to use requiring very little pressure to "chase" the threads so that a standard PL-259 screws on without any problem. Over the years having that die-nut has paid for itself many times for myself and friends who ended up trying to use metric connectors with American standard connectors. Danny, K6MHE |
