Regarding power used:
I was running 25w (minus a few dB of coax losses) into an 8 element beam (vertically polarized), and getting an S5 return on a 2x15 circular beam, with a mediocre preamp. I forget if it was RHCP or LHCP on the downlink at the time.
I don't have a power meter, but I could turn my 736R's Drive control about 3/4 of the way down before my signal got hard to hear. Maybe 5w or so? This was when the bird was about 10-12 degrees up, in a direction that has about a 5 degree usable horizon (there's a hill in that direction).
Hope that helps,
