I am in stalling my radio station in to the small "box room" on the 2nd
of the building and I have in the past not worried about a separate earth
the station. But as this station is going to be a more permanent arrangement
than my other previous locations I want to make sure that :-
1) the station is safe electrically. (of course the supply earth will be
2) protected form static (lightening etc).
3) has a good RF performance. (this means low resistance earth connection)
4) is as clear of EMC problems as possible.
So any one got some pointers or helpful hints on installing a separate
earth. The ground connection is easy 3 to 6 off 6' long 1" dia copper pipes
driven all the way in to the soil (I know it is a big is job but not
The bit I am puzzling over is do I use a heavy copper strap as used on
lightening conductors to provide a common earth for every thing or just for
static protection and then a separate heavy conductor to provide the shack
In either case how can I ensure that the earthing does not radiate RF (I
that making sure the aerials are correctly balanced with suitable baluns
the answer here.)
I did here about using RG8 type coax and connecting both inner and screen
to the hardware in the ground but only connecting the shack earth buss to
inner - any thoughts on this.
