If your building/home has windows that are filled with gas (Low E) these windows incorporate a metal based coating to reduce heat flow through the window. The coating is intended to block infrared radiation but it also can lower signal strength since it blocks the signals. Try the antenna on a wall directly beside the window and rerun the channel scan to see if that resolves the issue.
