I missed being able to be clear in my "other" post. If there is a
Beacon signal available from a POE satellite at 2meters there is an
Excellent 2Meter source of signal with which a person can use to Very
Accurately record the radiation pattern from horizon to horizon at all
azimuth angles. That radiation pattern will be the pattern of the Ground
antenna, not the satellite antenna. We have to assume the satellite
radiates equal in all directions.

The strength of the received signal is recorded into some program like
Excel as a function of time. The actual Az-El to the satellite is
published, or can be computed. So, it becomes fairly easy to record the
actual (ground based) antenna's radiation pattern which includes all the
environmental effects like trees and neighbors's houses.

Jerry you were clear to me. There are several things wrong trying to use
the sat to determine the patern of the antenna on the ground at other than
the specific pass. Low orbiting sats will start at a great distance as they
come over the horizon and get to with in a few hundred miles as they go over
head. The squnit angle of the sat antenna will change so the sat antenna is
not always pointing at the ground antenna. The apparent polarity will
change and that can make a big differance.

I have the KLM circular beam pair for 2 meters and 435 mhz on an az/el setup
and computer control. Also can switch from left to right circular and have
monitored the sats go over and sometimes have to switch left to right as
they pass for the best signal.

I have not tried it on a sat but for the Icoms ( it might work on others)
there is a program that will record the s-meter and draw a plot on the
screen . I have done it looking at repeaters and it does seem to work ok
for drawing paterns.
