It's not over till I damn well say it is over!! 
Whatever you say
Back to the track about antenna in the
picture. I would definitely not want to see such out of my window, those can radiate quite power. At max power for antennas of such size exclusion zone goes into roof of that house indeed. If somebody lives in the attic - it is not safe. Hopefully they do not use sector pointed at the house. Can't find exact model, but
Small Cell antenna of seemingly same dimensions (600mm height by 200mm dia) can take total 300W of RF power, have max 8 dBi gain. Other antennas in the list have up-to 13dBi or so.
