A beam is much more helpful pointed towards the horizon. When the
satellite is right above, it's pretty close to you and anything will
pick the signal up. You need more gain when the satellite is at lower
elevations and furthest away from you.
A relatively low horizontal loop should work great under most
circumstances. A turnstile is also a great Mode A antenna.
Caveat on this info - it's not from experience - it's from reading
archives on this board, old AMSAT newsletters, and old amateur satellite
books. I've only listened to a Mode A once, and that was on a 1 meter
diameter portable magnetic loop!

Think that would work ok? How far up would the reflector have to be off the ground or rather how close can I get it?
