[TenTec] OT: Lightning and Grounds

[Carl Moreschi]

My antennas come into the house through a grounding plate and the shield of
the feedlines are always grounded at my station.  I was just making the
point that all my electronic equipment is discinnected from everything.  I
can draw a circle around my station's electronic equipment that nothing
crosses when I am in "storm mode".
