I hope not fo promote terrorism, but I`m not judging the merits of
application nor advising anyone to break the law. I only advised how to
feed the antennas in phase as need be for radiation to be aiding around
the 360-degrees. As for circular polarization, I would refer any reader
to "Antennas" by J.D. Kraus.

Richard I've been amusing myself by trying to develop an antenna that
"receives" RHCP polar orbiting satellites. The coverage I trying to obtain
would suffer from the stacking refered to in this thread.
And, it seems so obvious that feeding the two antennas in phase would
produce maximum gain on the horizon, that I thought there was some special
requirement for this antenna's pattern.
In addition, I have assumed that the impedance mismatch for receiving
antennas can be allowed to be much greater than for transmitting. This
statement is directed to the fact that transmission line loss is increased
by VSWR, and the reciever isnt restricted to being the same impedance of the
transmission line.

snipJerry
I am presently working with circular polarised antennas for transmit,
These antennas are omnidirectional but does produce a choice of TOA
What exactly is the pattern that you are looking for?
I do not have any knoweledge of satellite work needs
