WF65 Twin core sat cable (or similar)

Bogger77

Any one know where I can get this type of cable.
I've run out of space in the conduit, but I'd like to run another 2 cables up (one for radio scanner, one for new sat reciever), I'm thinking of replacing the 2 cables already there (vhf and sky box), with 2 twin core cables.
There's room for 3 CT100 diameter cables, so 2 twins should fit.

Was only planning on running the twin cable for 10 foot and switching to regular single cable.

Am based in Cork, but would travel to most anwhere to get.

It's rubbish. If it's only 10ft then use RG59 for 75 ohm or RG58 for 50 Ohm. A pair of either of those is slightly skinnier than the "shotgun" cable.

You'd want solid core RG59 to fit an F-connector for sat and then fit BNC on the RG58 for scanner (or BNC on RG59 if the rest of cable is 75 Ohm).

I'm using CT125 from chimney Discone "packed" to fit on PL529 meant for RG213 to scanner, or some PL529's for RG58 can be drilled out for CT125.

75 Ohm vs 50Ohm makes little difference to scanner, and even on VHF/UHF transmitter on a real aerial (rather than a dummy load) is seems to make no signicant difference to SWR. Even mathematically the reflected power is not a big percentage using 75Ohm on 50 Ohm rig.

BTW originally the BNCs on 75 Ohm video were "50 Ohm" type. Nowadays you can actually get N and BNC in 50Ohm or 75 Ohm flavour, but the wrong one is more a problem for mechanical fitting of cable rather than performance. The ratio of inside of outer shield to outside of inner core sets the cable impedance, thus the cables, espcially on larger low loss kind the mechanical of crimp on screen or pin etc is the problem.

Thanks for the advice.

Time for me to sit down and really work out what setup I want, and make it
future proof, (this time).
