Do you have a cabling company that you use? We put in a small network of these at a sawmill just out of palmy with these... http://ubnt.com/nanobridge Very simple install. Cable from cabinet up to dish. Point the dish in the general direction of each other. We had four if them up in half a day. Only thing we found after the first one was test the cable before you click the lnp in to the dish as it is bloody hard to get it out lol. Wasnt 2km though. More like 1-1.5km. We put in the NanoBridge M5 which is one of the smaller ones though so I would assume the bigger ones would do you 2km easy. dont ask me what it cost the customer as I dont do the billing haha.
