I share your thoughts about a pattern range. I recently talked my

buddy
into writing a program that plots Elevation Plane patterns of an

antenna
when scaled to a frequency sent from any Polar Orbiting Satellite. I
use
it alot using the 137 MHz beacons sent from NOAA satellites. Some HAM
satellites could be used. There are also L-band beacons sent from the

NOAA
satellites.


That's an interesting approach. Thanks.


Hi "Sal"
If you ever get involved with that Pattern Range, Patrik Tast publishes
information on his program on the web. Everything Patrik does is *hobby
related* and available free. Nothing I do is sophisticated or difficult

to
reproduce or to improve upon.
I was using Excel to plot the RSSI level before I asked Patrik to make a
program to display the signal strength in polar form. I can get actual
patterns that Very closely resemble EZNEC plots.


Thanks. Whatever I set up will probably be for signal strength A/B testing
between antennas at a fixed distance.
