Hi Bill

I was reading this and wanted to ask you:

If I hold the AM radio to the earthing rod (going into the earth, that I've

grounded my faraday cage to) and it has a buzz, what does that mean?

Thanks

It means that it is not *clean*.

And it means that the rod may bring *dirty power* into the house.

Thanks .

But before I attached the copper wire coming from the room, there was

no noise on the earth rod - it was quiet.

And then when I attached the copper wire (which is connected to the foil inside

the room) to it, it started having a buzzing noise on it. I assumed it was

taking some 'dirty electricity' into the earth, if that makes sense.

The same goes for the earthing spike on the other side of the house, connected

to the 'mini' faraday cage I have my PC monitor in. No noise on the earth rod

until I connected it to the cage.

Thanks

Well, in that case, your shielding had a coupling of electrical fields from the

electrical wiring in your walls and appliances.

Hi

Thanks, but I don't understand the terminology. But either way, is it

still effectively grounded?

If it mainly buzzes only when the rod antenna inside

the radio is perpendicular to the ground path, then

there is certainly RF current going through that

wire.

A small magnetic field probe will tell if there is also

60Hz going through. If so then there must be another

path from the shield to ground, and the path may

make a loop near some magnetic field source

(like a power panel).

If the other path can't be interrupted, then, if you

are sure there is no risk of the shield ever becoming

energized by a hot electric wire, try disconnecting

your ground and see how you feel.

If there is no 60Hz current, then the other path

to ground may be capacitative only. Again

you might try disconnecting the ground if it's safe to.

If the ground rod is outside your shield, and there

is something like a noisy power line causing the

buzz, the rod might help. But the shield paint

is probably not going to do a great job with

those ~MHz frequencies. In a case like this,

adding some buried flashing (copper is best)

connected to your ground rod might be a benefit,

though it may not be worth the effort. An RF

grounding path should ideally be less than 8 times longer

than the width of the grounding straps or braids.

So 8' of 1' wide flashing connected directly to your

shield and buried would be pretty good if the

dirt is fairly conductive. If your shield is bonded

to a conductive floor then don't bother with RF

grounding.

Hi Bill

Thanks!

Trifield meter shows just more than 1 mG at the rod.

AM radio buzzes around the rod doens't matter how I turn it. Although I see

this morning it buzzes in the garden anyway, just much louder around the rod.

Had it ungrounded when I was building the faraday cage (with Aluminium foil) and

couldn't stand being in the room until I grounded it to two earthing spikes. So

definitely better grounded.

Can't trip the switch to the room as there are other rooms on the same circuit.

Thanks again.

See if there are other hot spots of magnetic field,

maybe you can find another ground connection

or source of the current.

If the orientation of the radio doesn't matter, it could

be capacitative coupling (voltage rather than current)

but if you are seeing a magnetic field there must be

current.

I should have added the idea of putting a choke

on your ground wire. But if you feel better with

the ground, you probably don't want a choke

(at least not there).

If the ground were making things worse I'd recommend

a choke of about 12 to 15 turns through a ferrite.

For a safety ground the wire must be thick enough

to pass as much current as the breaker allows

(it's a little complicated, but if you follow the code

of 14 ga for 15 amps you're safe... a smaller wire

should still be ok at 15 amps but it will take time to

trip at that current... the breaker trips immediately only

with a much larger current).

(More turns works better, but tf you do a huge number of turns you could

make it so the breaker won't trip.)

Note a choke blocks RF current but not RF voltage,

so it may not be that helpful for something you're

touching like a computer keyboard.

The main choke should be a low frequency ferrite.

I've gotten some from Newark but the really big ones

I've gotten surplus. You could also add a high frequency

choke (can have less turns) from a harder ferrite.

RadioShack sells rectangular split ferrites that are

big enough to do several turns around. You

can also get split high frequency ferrites there.

LessEMF has them too, but not sure what material they

are. I think I read that for low frequencies a split

ferrite is not as good. Definitely a bar is not as

good as a ring.

If you put a choke on a wire carrying 5 amps or so of AC

current the ferrite will saturate and it won't work. Unless

you wrap the hot and neutral together... then it's a common

mode choke. The currents cancel so it doesn't saturate.

Since the ground helped an RF ground might help

more. That means buried flashing and wide

straps or foil from the shield to the site of

the ground rod.

Thanks, Bill

I thought I knew a reasonable amount about these things, until I read your posts

and have to read it three times to sort of know what you're saying ;)

The thick copper wire on the inside of the room is splayed (so that its

individual wires are 'webbed' against the wall.

And then fastened to the rod outside.

Is this what you mean?
