[SPAM] Re: Canopy- silver? stainless?

[Guest guest]

I did a few quick tests this evening with my cell phone:

Signal:

Stainless mesh strainer, single. Upright and inverted. Phone rings

Stainless mesh strainers, doubled with edges touching (like a clam

shell). Phone still rings.

Stainless perforated cheese grater (long rectangle with open top and

bottom, phone held inside, grater held sideways). Phone still rings.

Stainless perforated strainer, single. Upright and inverted. Phone

still rings.

No Signal:

Stainless sheet metal perforated strainers, doubled (clam shell). No

signal!

Solid Stainless pot with lid off upright. No signal.

Solid Stainless pot inverted on wood pull out chopping block (free

standing). No signal.

So - I wasn't able to get stainless steel mesh to block the signal.

Perhaps the fabric is different than my kitchen strainers?

The perforated sheet stainless was better, it had to be totally

enclosed top, bottom and all sides to work though.

The pot with no lid was a surprise. Total blockage of signal, so it

must be the 2 inch high sides. No enclosure necessary with thicker and

perforated 18/8 stainless. Coverage on only three sides is all that

was needed to prevent the signal from getting through.

So I'm still reserving my opinion on the mesh fabric till someone gets

some and does simple signal strength tests like this.
