SUCCESS!

I rotated my attic antenna about 15 -20 degrees east and now I can receive Channels 22.1 & 22.2. YAY! I'm sure the new 4 port amplifier helped too.
Channels 4.1 & 4.2 signals dropped a small amount but not enough to degrade the digital signal.
Channel 22.1 is the "myTV" affiliate and 22.2 is "The Cool TV" broadcasting music videos much like the old MTV did years ago.
