[Antennas] single point ground question

[Chris Boone]

It's a single point ground (in two way sites using such, it is usually a
large copper plate that all grounds go to that is isolated from the wall by
thick standoffs). However, in a true single point ground system, you want to
weld the single ground to the plate and to the outside ground as
well....Lightning cant be taken for granted...Most folks usually don't have
the luxury of the electrical and phone ground being at the same point!
