[TowerTalk] Fwd: Connecting Tower to Ground Rod

[Keith Dutson]

I am not certain how those numbers apply to conduction of current, but it
seems obvious they differ from what is used by industry.  I have never seen
copper plated PL259's.  Same for pins used in commercial plugs/sockets.

Ahhh...Gold is not the best conductor compared to Silver
*Gold*: 2.24: Copper: 1.724: *Silver*: 1.59:
So both copper and silver are better conductors than gold with silver being
almost twice as good as gold.  Gold OTOH is tarnish resistant and is almost
like a lubricant on contacts

Silver easily corrodes and copper is not far behind.
