Bob,
Just a reminder, a QFH antenna is circularly polarized over the whole
envelope of the antenna. A sharp null exists on the back side. A one
wavelength, one turn has gain at low angle side radiation and a 4 dB loss
overhead, where the distance to the ground station is the smallest.
Certainly this is a good fit for satellites.
Turnstile antennas and patch antennas are linear polarized at the sides and
of course are the easiest to implement on a satellite.
My point is all circular antennas are not equal and having an antenna with
gain on the sides opposed to the center of the antenna is very desirable.
Art,
KC6UQH

Lets try this approach... As I said before, By the laws of physics, what
comes out one side of a circular polarized low gain antenna as RHCP comes
out the opposite side as LHCP.
Now given that, and the fact that someone in Maryland is in the center of
the RHCP beam, then by the laws of physics, the guy in California must see
mostly LHCP. No matter how much one of those persons demands that he
deserves the RHCP beam, by definition, someone else somewhere will get the
LHCP one, and the geometry changes at least every 10 minutes or so and every
time the spacecraft rotates a bit.
So one might say, "point it down" then only the person in Kansas will see
the main beam and those in CA or MD will be completely off the sides almost
70 degrees from the main beam. Mot people do not realize how LOW these
satellites are. The only solution is to put satellites so high, that "down"
is about the same to everyone (geostationary altitude). But then that takes
100 times more altitude, and that takes 10,000 times more power.
Better to just live with the laws of physics... I guess.

Hello Jean-Pierre
You are right, they have absolute no interest for us radio amateurs.
And this could be a problem, if this Russian satellites flies over
Europe and transmits their DOKA-B signals in FM (!) in the 435 MHz
frequency range.
Look for first hand infos in this PDF-document:
http://home.datacomm.ch/th.frey/Yubileiny-2.pdf
MiR(Yubileiny-2) is active in DOKA-B only in range of a control station
in Russia, e.g. Moscow.

Hi Art, KC6UQH
It is correct that a QFH is circularly polarized over the whole envelope
of the antenna.If it is left wound the polarization is RHCP and if it is
right wound the resulting polarization is LHCP.
By the way the point is the satellite antenna.
If the satellite antenna is made using two crossed dipoles mounted in the
same mechanical plane and are supplied with 90? out of phase than the
radiated polarization is RHCP along one axial direction and LHCP along
the other axial direction.
Since the satellite is thumbling orbiting in the space than the polarization
coming from the satellite to earth or coming from the ground station to
the satellite is continuing changing from RHCP to LHCP to linear passing
through elliptical.
The bad point is that a QFH can only radiate RHCP or LHCP depending
on it's winding direction so that using only one QFH the QSB generated
by the satellite thumbling cannot be completely eliminated and two
switchable QFH's one RHCP and the other one LHCP would be necessary.

Domenico,
You are correct, the crossed dipoles fed in quadrature when on axis exhibit
LH and RH circular patterns, but 90 degrees from axis they are linearly
polarized. This gives poor performance at low angles as well as requiring
both RH and LH rotations for a full pass reception.
Obviously the QFH antenna to be effective should point down at the earth,
with the sides pointing to the horizon and the backside towards outer space.
The one wave one turn can be optimized,(Length to Diameter ratio)to provide
best radiation at the horizon. This will give good performance when the
satellite is near zenith as well as provide improved performance at low
elevations.
Circular polarization does help to eliminate multipath and provide a steady
copy, even while the antenna is mechanically rotating with the satellite for
stabilization and temperature stability.
Art,
KC6UQH
