It does get pretty hot up there, although I've never actually measure the temperature up there I know it's not ventilated as well as it probably should be. I can put the amp in a closet but it will make the run about 30 feet longer.

My 3-way splitter isn't labeled.

Terminate any unused splitter ports... better yet, if you only need a 2-way splitter in the basement, then buy one and ditch another 4 dB of loss. (Or if you need a 3-way split, use that instead of a 4-way)

The attached drawing may be of some help... if nothing else, at least to be sure we're both thinking similarly.

I was hoping I wouldn't have to do that, but I'm not against it. I think it is probably the best way to do it.

The antenna is connected to the CM3414.

And connect the coax wiring so that a coax goes out to each Tv location from the 4 outputs of the CM3414 distribution amplifier.

This will put an end to the big mess of coax wiring.

Mounting the antenna on the roof is not very ideal, I'd rather keep it in the attic. I don't really have a problem getting the signal, I just don't have the power to run it through the current distribution setup.

Running wires from a distribution amp to the 4 TV locations is not going to happen. All wiring is behind drywall and there is no way to route new wires to the downstairs TVs. And that would remove the versatility of the current Setup where all the coax comes from a central distribution area and there is a drop in every room of the house. I would much rather go with the above suggestion of just removing the unused runs from the splitter to get the 8-way completely out of the system.
