There is a whole write up on the net somewhere on how to use the 75 ohm hardline connectors and covert them to a n conector or pl-259 with pics . If you need any let me know as i am a line tech for a cable company . Unfotunetly it will be hard for me to core the cable for you to install the connectors unless you are close by. If you get to that point , i would suggest going to the local office of your cable company ( not a payment center but one that the line techs and construction department works out of) and ask them if they can core them for you. The connetors installs differently than say a PL-259 would and are either a 2 piece or a 3 piece.
The coring tool actually cores out the dialetric and leaves the center conductor exposed with the shield. i do not have any here at the house to take pictures of it , nor be at work for the next month ( due to a back surgery). But feel free to contact me if you have any further questions.

You guys nailed it with the P3 500 from China. I also appreciate Ben's tip on how to use a PL259.

No markings on the jacket. It has a nominal jacket diameter of 0.58 inches (it looks to be the 'standard' black PE), it has a solid aluminum shield (0.51" OD), about 0.028" thick. The dielectric looks to be the PE foam. The center conductor is copper over aluminum with a 0.11" OD (about #10 gauge). It looks to be 50 ohm based on a rough calculation. > > The interesting thing about this cable is that it has a messenger wire molded to the outside of the jacket. It is about # 10 gauge steel. It is not wrapped around the coax, just to one side, about 0.2 inches away. When I say molded, I mean that messenger wire and coax have the same black insulator jacket with a rib of the same material between them. > > I am looking for a source of connectors for this cable, so any help identifying it would be appreciated. > > Thanks for your help in advance, > Rick, N5RB >
