Friends: I have a 8 bay HDTV antenna from which I receive some channels from the CN Tower but others come in weak. I set up a 4 bay antenna 10 feet behind and about 10 degrees to the left, which I combined with the 8 bay via a splitter. I found the signals became degraded, some not coming in at all. I disconnected the 4 bay, but same result. I had to physically remove the 4 bay in order to receive original signals from the 8 bay. Please tell me how to properly combine these 2 antennas. Thank you.
