Diplexor question (1 Viewer)

[Jake Gove]

Can a diplexor combine two RF outs from two DirecTV receivers?

I have two DirecTV Tivos and I want to get both to be available on all TVs in my 2 story house. I have a device that can assign one signal to a particular channel, and figured I could have the other be channel three.

My bigscreen is connected via s-video but for the other smaller tvs in the house, standard coax is fine.

You need something like a modulator to do a good job.
It looks like you want to combine channel 3 and channel 4 together.
Take a look here, many options.

I already have a modulator. I was wondering if a diplexer is what I need as well.
