It works because the ethernet cable is acting like an antenna for the
wifi card. You could wrap it around a hot dog, or just make a loop and
it would probably work just as well.

It might even work better without the cell phone, a high power
radio transmitter near a receiving antenna causes the receiver to "block".
My cell phone (1 watt on 900mHz and 2 watts on 1800mHz) is strong enough.

The salad bowl is a neat trick, and it would help.

Even better would be to use a USB WiFi dongle and suspend it in the middle
of a foil lined salad bowl.

Grumble. That was my idea, first. See:

The problem is that the salad bowl is not a perfect approximation of a
parabola. In addition, the USB dongle is not a proper feed with a
pattern optimized to illuminate the reflector. In short, it's a
kludge, but it works.

The salad bowl is optically reflective, so installing a point light
source at the focus will display the approximate radiation pattern on
the wall. At best, I get an annular ring with about a 15 degree
spread, which is far from perfect, but functional. Sorry, but I have
to give back by pile of borrowed test equipment before I could make a
gain measurement.

I only mentioned it because he suggested to use it to make his ethernet
wire coiled around a cell phone antenna work better. It was IMHO a better
idea to use an actual transciever instead of a passive antenna that
works via leakage.

It's a moot point for me, I'm limited to 100mw EIRP for WiFI
and terrestrial ham links.

Oh, my. Eric has lots of interesting tidbits on his site and youtube
page. I looked at a few of them to see if anything was going to explode,
but they all seem perfectly harmless.

I prefer http://northernmichigansolar.com/ for electrical wisdom.

I'm not sure i understand the point of sites like these.

He is going to need to put the cell phone over to the side of the
bowl so when he puts the bowl on his head the phone will be next
to his ear (the new alien signals he is picking up may be weaker
and harder to hear).

I use an old WOK as a parabolic and cut out for the dongle in the
center......it is very directional and it works.....
