I would recommend the Trango Broadband Trango Link 45.
It has an integrated panel and works on all 5 GHz bands.
The list price is $4,000, but I am an integrator with them so I can get it to you for just under $2,000. If you like, I can send you an order form. I don't get any profit or anything; you'll be dealing directly with them.
I have about 10 or so of these links from 3 to 20 miles and they have never failed, except for one case where we had a lightning strike. Even then the fixed it for $200 or so.
These are easy to configure and will give you about 40Mbps of true throughput at that distance. Let me know if I can help further.
