Help me w/ a wireless configuration, pls

I want HiSpeed internet at home. The only chance I have is to put an antenna in my yard to get service from provider that has put up a tower in our town. The problem is that I need line of sight to the tower. In order to get line of sight I have to put the antenna in the far corner of our yard. I have no electricity out where I need the antenna but I could get it there if I had to. Would it be possible to set up a wireless access point at the antenna to feed the internet to the house (about 100feet away) and if so how would I set it up. I’m basically clueless about wireless. Help!! Thanks.
