When only one cable run is available to use go with a Digiwave DGS0201 Satellite & Antenna Diplexer for its versatile design and easy installation. The Digiwave Diplexer sends the satellite programming to "back out" other televisions in other rooms using the same cable. This diplexer is DISH Network approved where two diplexers are typically required - one to merge the signal and one to separate it again on the other end.
