Cliff,
What, in this case, is very high rf frequencies? L-band for satellite
terminal use usually goes up to 2150 Mhz. I have heard/read of products that
claim to enable regular CATV coax to be used upto 3 gigahertz, instead of
the usual 862 Mhz, for data and other services.
Would you(one) use an F-connector with a braided core coax?

Our entire RF system is wired with RG-11 which uses male F connectors
with an
"integral inner pin". The center conductor of RG-11 is far too large
to use as a center pin directly.
And, yes there is co-ax with twisted center conductor. This is
done to increase the surface area of the center conductor to help
reduce the losses caused by "skin effect" at very high RF frequencies.
