Thanks all. I'll try the direct connect test for the rear TV. All of the cables are labeled. The coax labeled antenna is connected to the antenna jack on the box. There is no wall plate, just the box with a power switch. When I switch the selector box from Aux to Ant for the front TV the picture freezes. The box output jacks are clearly labeled, "To TV, From Antenna, From DVD" etc. I will revalidate all connections. Also the rear TV was originally connected to a splitter that has the coax for the outside TV. I direct connected the Rear TV to the coax input to the splitter. That is when I actually received the weak signal. There was no signal while connected to the splitter.
