You don't need anything other than "standard" coax. By that I mean,
whatever the manufacturer of the plus says. It'sits RG/59, use that.
You need to cut the coax how they say too.
I would certainly not decide to use a PTFE coax - use what they are
designed for. I'm not saying PTFE coax wont work, but what I am saying
is they would have been extensively tested with the right coax.
If you don't have the installation instructions, then I suggest you
get them. I expect you can find them on the web. If the worst comes to
the worst, I probably have the instructions for one.
As a matter of interest, what are people paying for SHV connectors?
