[Elecraft] Stealth antenna insulators

[Ron D'Eau Claire]

Has anyone actually measured the RF characteristics of the various nylon
lines available?

Nylon is hydroscopic (absorbs water) and so is not necessarily a great
insulator. I didn't know that and blithely used nylon as an easy-to-find
insulating material until I had a nylon standoff in an RF circuit
disintegrate quite unexpectedly. 

I've not tried it as an antenna insulator, but I have been wary of it since
that experience.
