The Zenith Silver Sensor (ZHDTV1), although a great antenna, is UHF only and highly directional; not a very wide beam width; I am guessing it is less than 10 degree (maybe someone has the actual number). Just by looking at your posted results, your needed width is from 8° to 339° for the full sweep and this is much too large for the antenna without re-aiming to the correct heading as needed. Even if you exclude the 2 farthest channels, 51.1 and 68.1 you are still looking at 8° to 83° and that too is just too much without re-aiming. Another thing to remember is that even though transmissions might originate from the same approximate distance and heading doesn't mean that they all transmit at the same exact power; meaning different results to you the end user. I also have to ask if you have any access to a patio, balcony or window where you might be able to try a wider beam width model not 100% "indoors"?
Maybe look at these. I am not 100% sure of your home and surrounding, so these are just ideas that might spur thoughts on better alternatives. What is your maximum distance away from the transmitters?
