Dumbo question (maybe). When I cabled up the multisat dishes, I used French sourced coax which was 17 vatc. After changing back to the motorised dish, I'd like to use compression fittings, but I'm not having any success with getting them to fit onto the cable. Either they're too slack or the other compression fittings I was given seem to distort on compressing. Any ideas as to the difference between 17vatc and say RG6 ?. I'm using a cable stripper/cutter and a compression tool (i.e. not a pair of pliers)
