I'm trying to design a point-to-point link, about 10 miles, that will carry a high percentage of a whole network's backhaul. So I'd like it to go at about 80 Mbps, MCS 12 in 20 MHz. The UBNT SR71-15 card can plug into a Routerboard and thus feed two antennas, or a dual-polarized antenna. I'd rather have one antenna than two. I can find dual-feed 2' dishes, but they're on the large side, with wind load and visibility issues. And I see a lot of single-feed panels, which can handle 11a-type traffic. I can run Ethernet into an external radio that comes in a panel, but that adds a hop and more complexity, and frankly most of the specs don't match the SR71-15's. There will be at least three antennas at each end, possibly four (backhaul plus local access). MiniPCI radios in, say, an RB600 seem easier to deal with. But who makes a standalone 5.8 GHz dual-polarized panel, something the 22-25 dB range (13-16")? UBNT makes MIMO sector antennas, and makes panels with built-in radios, but it doesn't seem to have a PTP panel antenna to mate with the SR71-15. ARC has one that works with its built-in enclosure system; do I just leave the enclosure empty and route the cables through it? (Seems hokey.) RADwin has one designed for its own system; I don't know how well it would work otherwise and it's way expensive. Suggestions?
