It looks like your fresnel zone is 14ft (according to a previous poster) and
you're currently using relatively low power radio waves.
Have you considered using something like Free Space Optics? For under $100,
you can build yourself a couple of RONJAs and test out what the signal is
going to be like - that runs at 10Mbit, and can stay in place as a backup
once you then buy a FSO device from a proper manufacturer (MRV make some
nice ones) and you're looking at 100Mbit for some money, 1000Mbit for quite
a lot of money and 10000Mbit for "it would have been cheaper to lay fiber".
I'd heartily recommend giving infra-red FSO a go, no Fresnel zone and it's
essentially bridged ethernet - no funky routing required, though I would
still set up OSPF or similar with it, to fail back to a slower link such as
