I'm preparing to go from a hand-held VHF to a hard-wired unit, and I'm contemplating a couple of ways to lead coax through the deck. Has anyone used the Cable Clams made by Blue Sea Systems? They allow you to put coax with a PL 259 connector through the deck and then apparently seal the cable tight. The benefit, it seems to me, would be using two less connectors, which might improve radio performance (plus make the installation simpler and perhaps less expensive). I'm just wondering how watertight they really are, especially after a few years of opening and closing to pass through the cable when setting up the boat. Otherwise, I would use one of those long threaded double-female connectors with two nuts (using two washers above and below deck) and a total of four PL 259 connectors. The PL 259 connector brings me to another question: Has anyone used the Shakespeare solderless, crimp-on connectors? Do they provide a solid connection? Thanks! Gordon M-17 "Sapphire" Milwaukee
