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.
