If you are not sure if your new TV is compatible with an antenna, you will need to reach out to the TV manufacture or look in the user manual. Two things are needed for antenna use... a coaxial port and an ATSC/digital tuner.
If you discover that your TV is missing a tuner needed to use your Mohu TV antenna, all is not lost. In order to use a TV missing a tuner or a coaxial port, purchase a digital converter box. This allows you to connect your antenna to the television and converter boxes have built in tuners. A digital converter box connects to your TV via HDMI or other means (make sure you know which connection you need before you buy) and allows the TV to receive digital TV antenna signals. A digital converter box is a one-time purchase with no monthly fees. One converter box is necessary for every TV that does not have a built-in digital tuner to receive signals over the air with an antenna.
