Comcast Digital Cable; Splitters?
Answer:
You have many options. The only thing that you have to keep in mind is that the more you split the cable the higher the chances of you loosing too much signal to the digital boxes.
I am asuming that you have all 5 coax cables going from your tvs, throught the walls, and down to a central point. This is called a "home run" installation instead of "daisy chain" install where each splitter is feeding another splitter throughout your home.
At the central point, one 3 way spitter that feeds (gives signal to) another 3 way spitter will work out. In this scenario, there are 3 outputs per splitter, one being marked with -3.5db and the other two marked with -7db. plug in the cable that runs to the tv with a cable box that is the furthest away from the central point into the -3.5db output. Then plug in the other cable box cable to a -7db output.
you will need to use a small coax cable "jumper" from the last -7db output, to the next 3 way splitter.
Another scenario, if you want to makes things simple, is to purchase a 6way splitter and a signal amplifier. You would first hook up the signal amplifier. Then you would feed the 6 way splitter, and just plug in the 5 cables to it.
I hope that helped! I am a communications technician. If you have any more questions, contact me.
Good Luck!
The three TVs lacking boxes will only be able to tune the analog channels unless they have built-in QAM tuners or CableCard slots.
