    tried mucking about with the antennas loads, no change. Cant chop trees as they are all in private gardens. The expense of a dedicated leased p2p line isnt an option really. ADSL with a VPN will be the only other option I think.

    Got a company coming today who say they can do a wireless solution that doesnt require a line of sight - so will be interested to see how this pans out!

    There is the mad scientist route, attaching a magnatron from an old microwave to one of the antennas will crisp those nasty leaves, birds and anything else out of the way it is something that you operate from a safe distance and a couple of brick walls away though

    Have you tried aiming the antennas both slightly upward above the tree line as there is an effect 'freznel zone' or something along those lines that causes signals to drop in angle slightly but it may only be over water. I heard a wireless engineer talking about it regarding wimax links over open ocean to an island located near Auckland.

    If you do want to try and go down the cable route, then def worth speaking to BT, as you can rent pairs of copper off of them connected to both buildings. Main disadvantage of this is the length of copper is from building 1 to phone exchange back to building 2 - so if the exchange is 2 miles away, you're never going to get much accross it.

    Can't remember what the service was called, or if they still offer it - last time i did this was about 6 years ago, but it worked out at something like £350 per year for the lines, and the install wasn't hugely expensive. You just put your own sdsl routers at each end.

    I'm pretty sure they do the same thing with fiber as well, but no idea of the costs, and if you haven't already got bt fiber into both buildings, its gonna be expensive!

    If not, are the tree's on the schools land, or somewhere else? I it feasable to loose a few of them? We've round trees really kill a wireless signal - obvoius question is does it improve in a month or so's time when they loose their leaves?
