No. .320 is actually solid sheathed or hardline. RG-11 is the usual braid over foil. .320 has a bit less attenuation than RG-11 with better shielding due to it's solid sheath. The application is a CATV drop cable though I could see it used for long DBS runs. No need to use it for video because baseband video only goes to 6Mhz. That's why the old mil spec RG-59 with copper braid, solid copper center conductor and solid poly dielectric is normally used.

As to RG-8, don't confuse your cables. RG-8 is similar in size to RG-11 but is a 50 ohm cable used in communications like to connect a transmitter or receiver to an antenna. It's smaller counterpart is RG-58 which you might remember from the CB radio days and the old thinnet computer networks. All CATV cables are 75 ohm.

You mentioned head-end cable. If you are talking about the cable used to interconnect equipment in the racks at a cable companies head-end, that would usually be either an RG-59 or an RG-6 size cable. Head-end lashup cable is a special highly shielded cable with a silver plated center conductor.

I am aware that RG-8 is 50 ohm. I've only used it for uhf antennae to da's for rf mics. Actually we usually used RG-8x from Belden. Who actually manufactures the .320? Is it Commscope, Belden other?

The coax thing always puts me between the charred walls of the dammed. So many different coax sizes and so many different connector sizes. I was buying these F type compression connectors from Ideal that was a 1 size fits all and they were $1.95 each, I know that's expensive but worth it for me but they stopped making them. I hate getting to the job site pull cable and then the ends don't fit!!

Just splice the cables together. Connectors are overrated.
