Smartenna+ emulates seven TV antennas to find the best OTA signal

Channel Master's new device can adjust reception patterns with the push of a button.

Believe it or not, some people still get their television signal over the air from antennas. It's one way cord-cutters can watch local television without purchasing a cable subscription. Getting good reception can be tricky, though. Channel Master's new Smartenna+ is an amplified, indoor TV antenna that uses an internal computer processor to analyze the signals at your home and choose the best one for you.

Made by Ethertronics, the antenna has seven different antenna reception patterns, which is like placing seven antennas around your room to pull in a good broadcast signal. It can also adjust the reception pattern with the touch of a button, which means you don't have to adjust any rabbit ears to get a better signal.
