PL259 Thread standard
"HRBE" wrote in message ... Hello to all, I have just bought a Ground plane adaptor off Ebay (yeah I know!) (China! 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 am thinking MFJ put out some antenna tuners a few years back that had some oddball so239 connectors. The threads almost matched up and youcould force them to mate, but it was not smooth. Also think they would send you some replacements for the so239s. |

Metric PL259's are quite common on some Japanese white stick antennas. 'Normal' Pl259's will not screw up tightly. I think that they are normally known as PL259(M) although I think that there is another designation as well. 73 Jeff |
