Hooking up Directv - newbie

[kslachowin]

I am trying to hook up my Directv to my Samsung Directv DVR/TIVO receiver. I have no problems when the coax cable is ran directly from my Directv dish to the back of the receiver. But when I try to connect a coax cable from the dish to another cable that is when I don't receive the signal.

Do I need something else to connect the 2 cables together? Does this make sense?

The second cable you are trying to connect, is it an existing cable company installed cable?

You need two cables from the dish for a TIVO box to work right.

The second cable was pre-ran through my townhouse. So it is currently not connected to anything. I went to radio shack and they said I probably need a diplexer? Is that correct?

How many cables are sticking out the wall outside your townhouse? And how many total cable outlets do you have inside the townhouse? I am not concerned about how many are or are not being used just the total number of each.
If for enstance you have only one cable outside and say four outlets inside then somewhere in the line is at least one cable splitter. You cannot split a satellite signal using a cable splitter.
