You are a good guy , taking care of others. . There is also ROKU/NETFLIX for 8 dollars a month.

Here is a idea , if the big oak trees are blocking to much signal then if the trees are close to the house and beyond the trees there are no more trees for some distance then it is possible to shoot under the the trees , pointing the antenna up a little to the transmitters. Or put the antenna on the other side of the trees.
