There is a little button (sometimes hard to see) on the wall outlet where you hook up the coax that will turn on (or off) the antenna amplifier. A light will show when it is on. Without the amplifier turned on you will NOT get any OTA reception. When you are hooked up to cable you need to have the amplifier turned off. Also you need to run a setup on your TV for either OTA reception or cable (with or without a cable box). I hope that helps.
