[TowerTalk] Right Angle Connectors

[Bob K6UJ]

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.
