Hey guys:
I did some experimenting this weekend:
I ran one coax directly from the large antenna (No splitters, pre-amps, or dist. amps) and all stations came in pretty well during the day.
I relocated the cable run from the opposite corner of eve to the closer corner of the roof eve. (Left side)

I tried bypassing the dist. amp, (Pre-amp only) but the picture was pixelating pretty bad. Without the pre-amp, the 5 TVs in the house got only a couple stations.
I re-installed the CM dist.amp and also closed/folded in the 3 longest elements and increased my KABC (177Mhz, the lowest frequency station) by about 6%. (see pic)
We also experimented by raising the antenna to the top of the pole, but it decreased the signal, so I lowered it as far as I could so it would clear the tile roof if I rotated it via the rotor motor.
I also replaced the pole with a Winegard 18 gauge steel one.
I need to remove the 2 splitters and try to combine them somehow, but the difficulty in this is that the 2 wired-in cables (Downstairs living room and master bed) are inside a TV box on the side of the house. (3 other TVs are connected to a splitter in the attic.)
Here's how it's all connected:
1. Antenna to CM pre-amp (exterior)
2. Pre-amp to CM dist. amp (attic)
3. Dist. amp to 4 port splitter (One goes to each of 3 other bedrooms.
The 4th goes to the TV box on side of house.
4. TV box connection has one 2-way splitter for both master bed and downstairs living room.
5. Coax is house grounded; pole is not grounded yet.
I'm pretty sure the coax is all dual-shielded RG6 only.
Would replacing the short coax between the antenna and pre-amp with quad shield have any significance in gain?
And do you think that a 5 port splitter would be best for our situation?
Thanks again for your expertise.
