I agree with Rohan,  Galaxy satellite dishes are very high gain
omni-directional antennas focused to receive a signal sourced at > 50,000km.
To mod up the Galaxy microwave dishes check out
http://www.ashtec.dyndns.org/ashtec/mods

However, you will certainly be able to do what you want with a hi-gain omni
directional (or sectoral) antenna on the hill and use the modified galaxy
dishes (or just hi-gain directional antennas) at the customer/user end.  We
have very successfully done this in both test and production environments in
both Canberra and Rockhampton.  If you do it right you can usually get
>2Mb/s synchronous at up to 14Km with reasonalby priced off-the-shelf
antennaes.

By the way, if you are delivering Internet content over this make sure you
have a carrier licence (or a nominated carrier declaration) or you will get
in big trouble. ;)

will get great range, but will only be able to target people in a line from
the dish, which might not be appropriate for a community  access point.
However, if your community is spread out further than an omnidirectional
antenna can reach, you may have to link everyone up with galaxy (or similar
homemade) antennas.
