Re: Anyone have experience with flectron shielding fabric

[Guest guest]

I have used some shielding materials. Flectron has nickel, which should

help at lower frequencies. For RF, especially microwave, you can do quite

well with aluminum foil

or metal fly screen.

Interesting. I guess I'm more concerned about higher frequencies then.

Wifi, Dect phones. I also found I have an inactive TV dish just above

my head. Any good sources for larger sheets of aluminum foil? Enough

to cover a wall? Also not sure what a metal fly screen is. I'll have

to google that. Thanks for your input.

If the dish has no power to it I wouldn't consider it a likely problem.

Restaurant supply places carry double width extra heavy duty foil.

Be sure to overlap the pieces by 3 or 4 inches, and get good contact

between them.

Fly screen is what you put on windows to keep the bugs out.

Thanks for the info. The dish is active (not sure whether powered) in

fact I'm in the process of cancelling that service and getting cable

internet. And I am directly under the dish. That room has the highest

radio signals in the house. I'm only using a zapchecker so my

measurements are relative. I can't check frequency. Odd's are it is

using WiMax.

Logic dictates that the dish, which focuses signals, is the most

logical source. Could be neighbors but I'll have to wait for the dish

to be gone to test. The cable (coax?) to the satellite dish is

connected to a linksys router with an adapter. So if it is powered it

would be via power over ethernet. I'm not familiar with how dishes are

powered or whether they are just passive.

Again thanks for your response. Any info is very helpful.

Just a simple question I have : I read it is necessary to ground the

aluminium foil. Then how to do it exactly. Cause again I'm very

ghetto. Using simple electric wire taped to the foil, well, it's a

bit unstable cause the adhesive tape can loosen, and then the

connection is undone. So any simple advice about that ?

Interesting, not sure how " grounding " rf frequencies would work in an

electrical system (lower frequencies). I know that lessemf.com has

pre-made grounding cords. I have no affiliation with this site and you

could probably make a grounding cord with an alligator clip yourself.

Where did you read about grounding for rf? I'd be interested in

following up on that.

I read it somewhere, better to ground the aluminium shield. I don't

know where I read it maybe here. Cause otherwise it just shields one

side, if there are waves coming from the other side, it will reflect

it.

The alligator clip, I have some doubt, the survival aluminium blanket

for example is very thin, so with an alligator clip don't know if

it's reliable.

Sometime mylar is only conductive on one side (usually the duller looking

side I

think).

A long thin wire is not considered an RF ground--although it will be

good enough for any 60 Hz fields. Grounding straps are used...

the frequency determines the needed width to length ratio of the strap.

On second thought, thanks, it could work better than just using

adhesive tape.

One issue solved maybe !

So what would an example rf ground look like. Clip? wire? What would

it be attached to send it to ground. Earth ground I assume?
