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.

Thanks to N3QAM and Ben. You guys nailed it with the P3 500 from China.
I also appreciate Ben's tip on how to use a PL259.

can't identify. 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.

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.
