Anyone thinking about purchasing these beware of a problem. It will not work with RG174, RG316, or LM100 cable. The barrel that the center conductor passes through is only .046 inch diameter. All three of the cables have .060 inch center conductor insulation so they will not pass through the barrel. It will work with RG178 cable as the center conductor insulation is .033 inch. Luckily I had RG178 in my stock of coax cable.
