Bccs: part 2

I'll post this in [EE] as

1. Some genuine EE content.

2. Aimed at the [EE]'ers who don't subscribe to  OT


As Bob has adumbrated, the original material and other like it should
be posted in [OT] as [EE] is intended for "real elecrtrical stuff such
as you can buold yourself".

The aim is to try (yeah right) to keep EE a pristine and happy  EE
place that will keep those with a more purist bent as happy as can be.

The original  post was entirely acceptable as an [OT] offering.

When I  got my first mobile phone I was interested in finding how much
the signal would be blocked by shielding. I tried placing it in a
metal office filing cabinet and viewing the signal-strength indicator
through a slot - little or no apparent change. The phone was also able
to be rung.

The experiment did not extend to working out how to enclose myself
along with the phone in the filing cabinet for speech tests, but i was
suitably impressed.

Obviously Faraday did  not build the filing cabinet and/or the drawer
slots made acceptably good slot antennae or ??? Bottom of cabinets are
often open and informal "slots" run up sides of drawers, so maybe more
shielding could be achieved without too much effort. Interesting
lesson though.
