I reside in a 2nd Floor APT with reasonable clear view of the major TV networks with exception of KCTS (Too low of transmission power). I have notice during the evening the 4 major TV stations have signal degredation with varying degrees of loss of signal. KIRO 7 is the worst offender with a complete loss of signal by 8pm and KCPQ 13 the least. Weather condition have no affect as this occurs in all weather condition. There is no time duration pattern when the signals start degrading. Using a Mohu Leaf Ultimate attenna & MonoPrice amplified antenna. Both antennas are place in the Loft window facing approx 72 degrees running thru a 2-1 signal connecter block then to a 1 in - 4 out distrubion block (powered but adjuster turn down to 0)

Any ideas other then opening one's wallet to COMCAST? I'd swear the TV stations have reduced the transmitter power since 2009 and may even reduce transmission even lower in the evening.
