"Airy R. Bean" wrote in message ... I was recently commissioning a 2M vertical antenna that had an in-built SO239. However, the thread on the SO239 was shorter than that of a PL259 to the extent that even when screwed fully home, the cable was not locked (Usually by those triangular pips on the end of the plug locating into the v-grooves on the SO239) and could swivel around with a correspondingly poor contact for the braid/outer. The solution was inspired by the new bathroom which we installed recently, in particular, the use of (Yorkshire?) no compression fittings with their olives to join lengths of copper pipe. The method is to completely unscrew the PL259's nut off the plug, and to wrap some braid off a piece of scrap coax around the cable end of the plug. When the nut is now tightened down, the braid is compressed and acts to lock down the PL259 by reducing the length of screw thread that is available to mate with the SO239 |
