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.




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.

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