Pictures very good. What looks like in the pictures , trees all around the house , but beyond that is not so many trees with more open space. Here is a suggestion , put a antenna pole beyond the the trees to the south ,

Before doing all that I recommed putting a tv antenna on top of the chimney , put blocks or books on top of the chimney so as to hold the antenna up off of the chimney metal cover so as to see what can be received through the trees. Run the coax in to the house through the front or back door and connect to the tv.
