[TowerTalk] Fwd: Grounding Question

[Hans Hammarquist]

This has been discussed many times.

My suggestion: Put a copper or aluminum plate next to your ground rod. Drill holes in the plate and place female-to-female coax feed-through in these holes. Let EVERY coax cable between our trx-es and antennas pass though these feed-throughs. Also pass your power cable, with ground wire attached to the plate, though the plate and groud your surge protector in the plate as well.

When (if) a lightning strikes, all your equipment will see a minimum of voltage across your equipment, something you want. Remember, every access point in your shack has to "stay close" so an outside surge doesn't get a chase to develop current though your (expensive and/or hard earned) equipment. Done right, all (or most of it) current from your cables, running in and out of your shack should be shorted out by the plate.

Good Luck and 73 de,

All -
     Our club is putting up a new shack. I have been reading Steve 
orris book "Up the Tower" and would like to emulate his "Single Point 
round System." He emphasizes all antenna cable shields and earth 
lectrodes should be attached to a common point before the cables enter 
he building. I must be misunderstanding  something . How do I attach my 
oax shield to the outside common point and also attach it to my radio 
nside the shack?
                                                                         
                                K4KGG,    Larry
