In this 20 miles does he have Line of Sight (LOS)? A wireless protocol, Mag Grid antenna, and an .5-1.0 WATT amplifier could do the trick. But he needs to watch his DB levels so if he does use the 1.0 WATT AMP he doesn't go over the un-licensed FCC spectrum.
You're not going to do a high bandwidth link 20 miles in ISM with a permitted EIRP (I think 4watts). That doesn't seem to stop a lot of people from putting a 20+db gain antenna on a 1watt input for this stuff, but 50 watts EIRP isn't anywhere near legal.
