They do the pressure sleeve type of PL259, which has cable clamping and a ferrule for the braid similar to that of the better sort of BNC and N type connectors. Not sure if they are actually more robust, but they are certainly more waterproof and generally more reliable and nicer all round than the usual sort of PL259 stocked by amateur radio suppliers. The usual things seem to be made of some special alloy of zinc and cardboard that resists any attempt at soldering or otherwise connecting the braid, and rots away at the first hint of moisture. Why they are popular is a mystery to me. Cheers, Jim Moritz 73 de M0BMU
