An individual at
http://www.dishstore.net gave me a solution.
It is a
Channel Plus SVM-24 Quad-Channel S-Video Stereo RF Modulator with IR Control. This will alow me to distribute the 3 signals from my 2 DISH receviers using my existing cable plus the OTA Antenna.
My
satellite receivers will also be on RG6 with this solution. When I bite the bullet and upgrade my TV to
HD I'll be able to route RG6 to that 1 TV, I'm not interested in distributing HD to the other locations.
