Antenna is installed on the roof of our single story house. According to installer it is properly aimed towrd Mt. Wilson with narrow end aimed at the transmitters. Installer confirms that antenna clears roof of our next door neighbor's two story house with no obstruction. Installer's position is if antenna was not properly aimed and/or did not clear next door neighbor's roof we would not be getting full signal strength (full bars) as we are now thereby ruling out any improrper antenna direction or nearby building height obstructions.
Does full signal strength read on tuner actually proove that antenna is unobstructed and correctly aimed?

We are no where to close LAX flight path. According to member "Electron" antenna should be aimed at 65 degrees. Is this a typo as it was my understanding fin speaking with all professional that antenna should be aimed at 45 degrees? What's strange is that pixilation occurs about every minute on every channel. Before I attempt to rule out any electrical interference as that will be a very difficult and tedious task I would greatly appreciate any and all follow-up feedback. Thank you.
