What is the “cliff effect?”
With traditional analog signals, the farther away from the transmitter you get, the weaker the signal will appear. If you go far enough the signal will get noisy or snowy, but may still remain watchable as the signal degrades. By contrast, digital signals adhere to the “cliff effect.” Basically this means that you either receive the signal perfectly, or not at all. If the signal is strong enough for your receiver to process, it should look good. If it is not, you will see nothing. With digital signals, there is no in-between.
