What is a digital antenna?

A digital antenna is a device that allows the user to receive digital television signals from varying distances, depending on where they live. There are three main varieties of basic indoor antennas that will allow the user with a strong television signal to receive digital signals. These are the UHF, VHF and combined UHF/VHF. There are other models for homes that receive weaker signals, including those designed for placement outside of the home.
