I was wondering about this today. My inside TV receives 36+ channels during a scan. But my outside set up gets 12 at best. So I decided to test my hunch on this. I moved my Furrion back inside and scanned. Outside it got 12 channels, inside it got 39 channels. Only difference that I can come up with is I am sure the booster is working on inside set up, not sure it boosts outside hook up.
I run a Dish tailgater for inside TV, 36 channels is thru antenna not Dish. I want to run HDMI cable from outside TV mount to my Dish receiver inside, then I don't care what antenna picks up.
