Consider yourself fortunate. By combining two identical antennas, you have reduced the signal power from each by more than 50% which may result in weaker analog signals appearing noisier (snow). You are also receiving reflected signals via the opposing antenna which will contribute to ghosting on analog channels.
The most reliable method of reducing snow and ghosting is to use one antenna with high gain and directional sensitivity. For valid reasons, you have chosen to do the exact opposite, you have built a low gain, less directional antenna system. Compromise is often needed when building a working antenna system.
As Canada transitions from analog to digital, you may see everything get better... CITY-DT (real channel 53) appears on your report but may or may not be on the air yet. If you have problems receiving new digital stations as they come on line, be prepared to revisit the need for A/B switching or a rotator. In an all digital environment you may also consider the use of
network attached tuners.
To distribute to multiple sets, I would recommend trying a passive splitter with the exact number of ports needed to serve all active sets. If you loose some signals due to the splitter loss, add a distribution amplifier such as the PCT-MA2-M, AKA Channel Master CM-3410. Amplifiers overcome loss after the antenna, they don't fix ghosting or signals mixed with noise.
Rule of thumb: One amplifier/preamp
can be too many, two amplifiers
are too many.
