wifi through forrest?

Is it possible to get wifi through a Forest if the source is only one mile a way?

what kind of antenna do I need? and any thing else?

Yes, it can work. My grandparents live over 1 mile from the nearest 3g provider tower, within a dense forest. They have Sprint mobile broadband and it works. Im also here to figure out the connection names and an antenna so I cant recommend that yet but I can say it works. It really all depends on how the signals scatter/reflect/refract
