Wanted to update on my results.
I found that positioning the antenna in the attic seemed to cure my breakups. Now I have run a cable from the antenna in the attic to the living room and after a few days of observing I am having zero problems with all my major local stations, even WADL! I can't quite get enough reception to get the broadcasts from Windsor (CBET) though.
Maybe sometime in the future I will try changing the setup with a splitter or filter but for now I'm quite pleased with my setup and reception.
Rabbit thank you for the wealth of information. Seeing that it's working without compensating for overload it seems to be that multipath reflections were likely the primary problem and a cleaner elevated path was needed.
