Roger,
Now thats interesting, I see what you are seeing Roger. it shows on the
drawing that the
insulator is LCP and in the revision notes, the last revision states
that the LCP insulation material
was incorrectly called PTFE and was changed to LCP. I found this
definition online:
*LCP* (liquid crystal polymer) - very stable, inert, and unreactive
dielectric material used in electrical connectors.
The Amphenol connector specifications state that the insulation is PTFE
Any chemists on board ? Perhaps LCP is a general name for thermoplastic
and PTFE is one type of LCP.

LCP. What's LCP?

OK guys, I am confused. What is the insulation in the Amphenol
83-1SP ?
What type of teflon is it ?

Where did you read that Amphenol used PTFE?
I have never heard of that.
BTW, PTFE is never clear, AFAIK.
In any event, PTFE is greatly inferior
mechanically, and has no electrical
advantage at HF, or even UHF. It's
high temperature rating is also of no
consequence for most ham applications. I
don't know why any knowledgeable person
would even want it, except in some
corner case like a common mode choke
made with PTFE coax.
