Re: Horizontal Polarized Antenna

But some satellites are magnetic stabilized to the earth's
magnetic field and so these satellites are horizontally
polarized nearer the equator and vertically polarized near the
poles.  And very predictible in between.

On the RAFT re-entry web page are two horizon views of these
changes in polarization for such spcecraft.  The two views are
about 30% down the page:

A correllary to this is that when these satellites are due south
of you (in the N hemisphere) the antenna is pointed right at
you, so you are in a null and signals are weak for a while...
