If you only are running satellite and do not care about any other reception options the wiring is simple. Run your rear TV off the coax connector and run a 3 wire lead from the other output of the sat box to the front TV. Your front TV signal will be much cleaner and your rear is a simple plug and play. At my house I run 2 receivers with the LR and guest room run off one box and the MBR and wife's office run off the other box. The secondary TVs are run off a 3 wire as the primary TVs were hardwired with coax when this house was built. If our guests want to watch TV in the GR chances are we are in the MBR running off the other box.
