I wired my house with data cable and coax to every room. The data cable is terminated and ready to go but the coax is a different story.

I've got 40 RG6 runs that are 15'-100' long. Am I ok to use a 25db amp and 13 4-way splitters? Or maybe a 2-way splitter and 2 25db amps followed by 4-way splitter? Will I have too much attenuation? I'm looking at the Blonder Tongue ZTA-25. Is that a good choice?

I'd really appreciate any recommendations or suggestions.

Thanks.
 
You'll likely need an amp for splitting it that many times. You'll want to go with splitters that have a low db loss per leg. Why so many hookups though?

I put at least 1 drop on every wall in the house. Will I have a problem with the different lengths of drops? If I amplify it so the long runs are good, will I have a problem with the short runs?
 
I don't think so but I haven't done that many drops myself I usually plan ahead and know which walls will actually need the drop and will sometimes provide an extra drop just in case. You may want to look and see if you can find a home distribution amplifier with that many outputs or do one five way splitter (low db loss) into five 8 way distribution amps. Or you could just put all of your short runs on one splitter and the rest into distribution amplifiers.

Actually I thought I was planning ahead. I thought it would be easier to run them with the walls open than after.....

Thanks for the links.
 
Well, in all honesty I don't see this working out too well for you. A better bet is to figure out how many you will need active (which should drop it to something reasonable like 8), put the splitter in the basement. If you ever change the room arrangements, just switch the line on the splitter.

EDIT:

Okay, it should work okay with those uber amps, but if you're considering digital cable on any of them that might be a problem, I would just label the runs well in the basement or utility closet so you'll be able to change as needed without having to tone out 40 unmarked lines.

One 8 way splitter should be fine with your signal from the cable co, I would start with that and see how it goes.

EDIT 2:

Oh, and make sure your fittings are good and find a decent splitter with good shielding. Those little light weight ones at Radio Shack/Walmart will help introduce ingress in your system.

Speaking of ingress, that's all the more reason to not connect up all those outlets.

Why is digital cable more of a problem?
