Connector insulation

siver/silver/teflon or silver/nickle/phenolic

bakelite - is this the same as phenolic?

Delrin insulating material is a little better but still can get soft at soldering temperature.

Teflon insulating material is very good and are increasingly available.

Don't use cheap nickel plated connectors, use PL-259 connectors which are silver plated and the connector metal is machined brass. They should also have a silver center pin. Insulator should be Teflon.
