[Elecraft] N fittings

[Stuart Rohre]

My understanding of the place to place silicon grease is NOT upon the
outside of the connector, but rather in the interface between male and
female connectors.  The idea is to exclude moisture pooling on the insulator
between the center pin and the outer shell conductor.

However, if you over wrap a coax connector with a good quality electrical
vinyl tape, and cut the end, rather than stretching it to break; you can
then overwrap with coax seal, Dux Seal, or self amalgamating tape lapped 50
percent, and have a long lasting but recoverable seal.

N connectors by their very construction do not typically need the addition
of silicone grease.  They have adequate fine threads and tight fitting
interfaces between plug and receptacle.

I prefer NOT to seal with silicone grease to enable inspection of the
connectors every year.
