[RFI] [TowerTalk] Back of desk grounding buss

[Gary Smith]

That's what I have in my shack. It is bolted to the underside of the 
desk, radio, amp and so forth are attached parallel to it the outside to 
a 8 foot long ground rod.

How to drive a ground rod? Get  short 1/2 inch id pipe nipple about 4 
inches long and screw a a pipe cap in one end.

With a helper to hold the rod vertical, get on ladder where you want the 
ground rod to go.

Slip the pipe nipple over the grounding rod, hammer on the pipe cap. 
This way you won't damage the rod.
Don't forget to get what's called a "Kearney clamp" to attach some old 
coax, (tie both inner and outer shield together) from the buss bar to 
the ground  rod.

Its surprising how installing what I call "the rest of the ham shack 
install" helps.

Pardon my wandering but ... just in case, now lall on the list know how 
I have cured bugs in other ham's shacks.

If aluminium, again, how large (I normally have round up to about 3" diameter sitting in the shop, as well an AL plate (various sizes, 3/16 thick up to 6" wide is everyday, and I have angle up to 5" wide legs, 1/4" thick around, and blocks up to 2" thick and 4" wide hanging around
