Issues Surrounding Installation of a Cell Tower?

But They Look Terrible as Trees asks: "My company has been approached by a developer who wants lease a section of our property to install a cell phone tower. The tower would be somewhere between 50 and 110 meters tall and would be located about 250 meters from our main building. I am curious what types of interference and other issues anyone may have noticed having a cell phone tower in the vicinity of their facility, such as disruption of 802.11, VHF radio, aesthetic issues, complaints from neighbors, or truly bizarre plots. Has anyone built their own tower and then leased space to providers on the tower?"
