Here is what I have and what I am hoping to do. Currently I have a cable tv package and a Dish 722K DVR. I also have a Channel Plus frequency-agile multi-channel modulator. My intention is to send the composite signal from TV1 & TV2 along with a couple of other sources as CATV channels out of the modulator. I would then like to combine those modulated channels with the cable tv channels and send all channels to 3 TVs (1 in each of our 2 bedrooms and 1 on our dock). So, I'm thinking I need something with 2 coax inputs that will combine the modulator and CATV signals and then have at least 3 coax outputs to go to the 3 TVs I want to send signal to. Also, I assume this "something" would need to amplfy those signals it is sending out? Don't need to boost, signals are good as is. I already have RG6 cables runs in place. So, I'm looking for suggestions by make, model, etc. Links appreciated. Thanks.
