1 cable for all!!!!

[vprada]

Hi Everybody... i was wondering if there is a way to feed the coaxial cable coming from my dish to the existing cable infrastructure in my house... As i have several cable TV points in my house, can i use the existing cable to feed my cable box and my receiver???
Is this possible??

thanks for any advice
Best Regards

Probably not.

Your existing house cabling is most-likely RG59 coaxial cable feeding multiple locations in the residence via cable TV splitters. Whereas you might just get acceptable performance with RG59 instead of RG6, the cable TV splitters are a definite show stopper.

On the other hand, you can use a diplexor to add the cable TV signal onto the satellite cable then another diplexor at the satellite receiver to separate the cable TV signal back out, if that is at all useful to you.

Well, probably there is a way to do it. Most of the Dishnetwork technicians who install Dishnetwork dishes, they deliver the cable wire through the cable outlet, the do it? So if you have somebody who can do that for you, its really doable.

It's certainly no problem to use existing cable to distribute programming from your receiver throughout the house. At the very worst, you might have to add an amplifier at the RF output before you split it off to the various rooms (if you had a ton of TV sets hooked up).

But, the biggest problem is...everyone would have to watch the same channel on the sat receiver! Because there is voltage across the coax line between the dish and the receiver (used to power and control the LNB), there's no easy way to run different receivers at different locations all sharing the same coaxial cable going to the LNB. Signal levels aside, the individual receivers would have to watch the same satellite (and same polarity transponders), and one receiver would have control of the LNB and all others would have to be DC-blocked, meaning they could not control the LNB.

Now, if you had a lot of money and time (and were just plain nuts), you could set up a bank of satellite receivers, each of which feeds an RF modulator on a different channel, with the whole mess feeding the cable. But, then you've just re-invented cable television!
