First off the FT-817 makes a nice satellite rig even though not 
cross-band duplex.

IN stepping up from say HT and Arrow to a "permanent" antenna there 
are two choices:
1)  A good omni-directional antenna with preamp, or
2)  A small yagi mounted at 15-degrees elevation and rotated with a 
cheap TV rotator.

If you can afford both #2 and a preamp that is even better.

Sounds good.  I used my 3-element 20m yagi for mode-A AO-7 quite 
well, but my 2m Lindenblad was not adequate for uplink with 50w.
For mode-B AO-7 you probably need a yagi with preamp (others more 
AO-7 experienced feel free to confirm or refute).

As they say" "been there, done that".
