Seems plausible... Comments from the WiFi folks?

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:

<http://groups.google.com/group/alt.internet.wireless/browse_frm/thread/61088cfb1efa861/>

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.

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