[Elecraft] Is there a "grounding" Elmer on line?

Nothing personal, but there are problems with the advice quoted below.

The archives of the "TowerTalk" reflector are a good resource, which
will in turn point you to various authoritative sources, along with
allowing you to read the discussions and different situations brought
up. Start with a search on "towertalk single point ground", that you
can begin using the search panel on the left of
http://www.contesting.com

There are many instances of small gauge wire being evaporated by a
direct strike. #4 is the smallest regarded as direct strike
survivable. Conservative installations use solid flat ribbon, or #2 or
even 1/0.

Spend a couple of entire evenings in the archives and get yourself up
to date.

73, and may you never wonder what evaporated your wires,

Guy, K2AV
