As I previously mentioned I do not have a signal strength meter and
used the standard Linux utility "iwconfig" to produce some sort of

the value of the increments that the ratio is accurate.

As luck would have it, I found an abandoned TV "cable" antenna - as
used here "cable" is received on a 3 foot dia. parabolic antenna and I
will probably try that at some later date.

My question is what makes you think that these two "dishes" are
Parabolas, and not just dish shaped? I would bet that the TV dish will
work significantly better than any dish shaped reflector, simply because
it will have the correct mathematical shape, and the Focal Point will be
defined properly by the designers.


I don't particularly think that the cooking dishes have a correct
parabolic shape. I was attempting to solve a problem with what I could
get my hands on. The discovery of the "cable TV dish" came shortly
after I had completed the 17" wok.
