So many things not included in your original post so I will list options
Option 1: SD video (NTSC) from Single receiver in FRONT to all TV's.. Yes that can be done.
IF you have a wall plate with a switch, a light and a 12 volt outlet
OR if you have a winegard SENSAR PRO YOu feed the To TV out on the sat receiver (if it has one) to the CABLE port (center or port labeled Cable) and turn the Switch or device OFF to send Sat To all TV's
Alas if the Receiver has only HDMI out you are going to need to buy a mini-television station (HDMI modulator) to do that or you will need to run an additional HDMI cable to the rear.
IF you are running TWO Sat receivers, one front one rear. Well just use both outputs on a DISH type antenna or you can get a Digital Switch for other types. Your sat equipment supplier can supply.
But yes, Depending on the receiver and a few other things it can be done. need more info before we can get specific.
NOTE Best method is to run HDMI cable to the rear from the front.
