[amsat-bb] antenna opinion?

I am going to put up a simple satellite antenna system. Simple means, that I
won't be able to control the polarization, I am going to use linear 144-432
beams. I will be able to rotate AZ of course, AND elevation.
Question is,,, how big of beams (how much gain) do I need for each band. I
don't want the pattern to be so tight I am constantly changing the rotor,,,
would something like 8 ele on 2 and 16 el on 432 do the job? I can use a
pre-amp on receive (separate coax lines) Any recommendations for antennas? I
just don't want to go through polarization switching.
And,,, would it be any benefit to turn the beams somewhere between
horizontal and vertical,,, at a 45 degree angle, for polarization? Or is that a waste
of time, or would it make things worse.
