In theory, it should be possible. A compressible center conductor
that shrinks in proportion to the outer conductor diameter.
But, I'll leave that for others to ponder.

Well, our cans are UHF connectors.
Isn't that hilarious? "UHF" connectors really good for HF, on VHF
cans. The radios are all N, and my preamps are BNC or SMA.
Life's like that some days.
If I had a choice, I'd change the cans to N, and the amps as well,
but at the moment that's what I've got.
At least I worked out how to put cheap crimp-on N connectors on the
FSJ1-50 jumpers along with the UHF connectors. Hopefully I can make
up for the icky connectors in the nice jumper cables.
This measurement thing is something that always bugs me in antenna
designs too.
When you're talking about an HF beam, little things don't matter, but
when you're talking VHF or UHF, I do think it's important to show
WHERE you're taking the measurements from.
