As always , trees and tree leaves do a real fine job of reducing or blocking Tv reception and so do buildings and other obstructions including your own house.
It is best to install the HD7000R antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own house.
