We needed this for my mother in law on the road and it works great. It covers about 300-400 feet with trees and small hills. I'm sure he would have gone further if there hadn't been any obstacles. It also brings a strong signal to the family home next to her at about 150 feet (indoors). So I was very impressed. I installed it at a height of about 15 feet. If we could go higher I would think the coverage could be greater given their terrain.
