You don't say how far from mt wilson you are and what type of antenna
you have and whether you have a direct line of sight to the towers. All
these affect antenna reception. Also multipath reflection can greatly
affect reception of dtv. The hdtv primer site has some useful
information on antenna installation:

Since you have some long cable runs and split the signal you might
consider adding a preamp to your setup - something like the channel
master 7777 would probably help boost the signal to overcome the cable
and splitter losses.
