You can set up a commercial UHF or microwave link, but that could prove
to be expensive.  A full-duplex system requires special equipment
(duplexer, split xmit and recv frequencies, etc.) on each end.  Have
you considered a laser based communications system?  We had one here
a while ago to ship data between buildings located a block away.  It
didn't work as well in rainy weather, and the cheap lasers weren't
really intended (or suitable) for 24 hour a day operation.  But the
system functioned.
