Seems I have built a giant faraday cage, on a concrete slab.
Need some feedback about grounding: here's the question:
1. Assume faraday cage ground is the station ground,since
the station is contained within the faraday cage. (Am using
2 4 inch copper strap to outside perimeter ground rods.
2. everything's ground connected to Faraday cage (metal)
single point ground (bussbar)
3. Told I should ground the tower to the station ground
(which is also grounded to cage)
4. Have made a provision (option to break) ground outside
faraday cage to station ground outside )its a small
1 foot gap. Faraday cage rests on concrete slab.
Have heard two schools of thought. National Electric Code
says common point ground for everything.
Other school, what I read on reflectors, though, is that lightning can jump
from your ground system back into your shack, if your shack
is grounded when the strike occurrs (like feedback)
This doesnt sound like common point is any good here...
My soil has clay, and goes down 4.5 feet (max depth of
ground rods..8 of them) to solid rock, Im at 2050 feet elevation (mountain)
and have one addittional ground wire option to the well casing
which goes down a few hundred feet (currently connected to station
ground -the perimeter groundrods.
My email is MEcker@peoplepc.com - bottom line, want to
protect gear (usually unplug it and throw coax/rotor cable
outside when not using, but would like to keep all the ground
wires connected without reconnecting those as well.
Any thoughts?
