Very helpful advice. I was wondering of there were any DIY cable experimenters here after all. I studied teflon tape and acquired the heavyweight "gas service" yellow PTFE tape from a reliable hardware store here in town. It's Mil-spec and quite a bit thicker than the white stuff and has an excellent dielectric constant (around 2 at 1MHz)
The braid on my cables is nicely restrained by an intact length of ordinary PVC(?) jacket at each end, so it can be carefully handled without coming apart.
Your advice about the physical constraint is very good. I am considering using the thinnest (20-mil) "self-sealing" silicone tape to wrap the cable again after wrapping with the teflon.
What's better than PET for an outermost (essentially decorative) jacket? How about glue-lined heat-shrink tubing- probably polyolefin? Provides the physical restraint.
