I use a 5 element on 2 meters and 9 element on 440. I have mine permanently parked at 25 degrees because of some ground clutter I have to clear. I have the 2 meter set for horizontal polarization and 440 set for vertical polarization. I would suggest preamps for both bands.

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.
