This is a good antenna if you are in the city or suburbs where the antennas are. If you are in the city close to the antenna do you not use the amplifier for better result. As you get away from the antennas and the signal is weaker use the amplifier (included). To clear a couple things up, you are not going to get CNN or ESPN this is for broadcast channels not cable or dish services. It will not pick those up. You will get a lot of channels and they are adding more channels every day. Second you are going to get fantastic up to 1080p picture on your TV. Better than cable because it is not compressed. The channels are digital with a max resolution of 1080p. At this time there are no stations in the US that broadcast in 4k. This is a really good antenna if you don't want to pay an arm and a leg for cable and still want a good number of channels.
