[TowerTalk] Right Angle Connectors

[marsh at ka5m.net]

Well, Amphenol uses PTFE in their RF 83-1SP PL-259 Coaxial Connectors and RF
83-1AP UHF Right Angle Coaxial Adapters

>From DX Engineering's website:

Amphenol RF 83-1SP PL-259 Coaxial Connectors

"Tough PTFE dielectric insulation further ensures the best performance for
your application."

Again from DX Engineering's website:

Amphenol RF 83-1AP UHF Right Angle Coaxial Adapters

"Dielectric: PTFE"

I use only RF 83-1SP PL-259 Coaxial Connectors and have never have a problem
with one.

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.
