[TowerTalk] Fwd: Back of desk grounding buss

[Hans Hammarquist]

Hi Charles,


I dare to say anything conducting seems to work. It's hard to tell exactly until it is tested. I used aluminum foil to screen off  my entire shack (which probably is an overkill but a 1 inch strip (or wider) 1/16" thick or similar should be OK. Anything else with similar surface area such as pipes, square stock or similar should also be OK. Any conductor such as copper, aluminium, brass, bronze probably even steel would work. I, myself, is using a 6 " wide Al strip behind my radio desk. That same strip is connected to my, close by, tower for the completion of the grounding.


Best 73 de,


Hans - N2JFS

Hey Gang,
Sort of antenna, sort of RFI, more safety..

I've decided my back of desk grounding situation needs to be improved 

Now, we all know the standard is a nice, thick copper buss.  Question is, how 
thick? - this will then be run down to the panel/ground rod

Is Brass/Aluminum/Copper PIPE a valid alternative?  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

I intend to silver braze most of my connections, but obviously that won't work 
to an Al  plate,  That I'd drill, tap, and either use studs with nuts, or screws

Again, we aren't talking the wall pass through here, but the buss at the back of 
the desk
