How would I combine Signal from my antenna with signal from my cable company at my Media panel?

(merge with coax thread) basically you buy a combiner and plug the cable and the antenna into the inputs and the output goes to your panel. you can buy splitters which also can serve as combiners.

Not quite sure what you want to do BUT I don't think you can simply combine the output of a "landline" cable line and a satellite output into one coax with an el-cheapo splitter.

If that's what you want to do, you'll have to use some A/B switcher.

something like this

No I cant use a combiner sinister crayon, or channels 3,6,9,10,11,13,21,31,58 will have ghosting from the Antenna channels. Im planning on buying a antenna (UHF/VHF) running the cable down to my media panel, and hooking it in with my Cable line. I came up with a system of modulators and de modulators that would work for the most part, but the price is unbelievable. (upwards of $400) Basicly deModulating the channel with a tuner then modulating it on another channel unused by my cable company. I cant use a A/B switch or I would be running down to the basement every time I wanted to watch free to air.
