We have an outside tv antenna. They are very large and have to be mounted up high. We had a chimney mount before we moved. You might use an antenna tower if you can find one. The antennas and tv signals are digital now, so be sure you do not use an old one. They can be purchased at home improvement stores. The reception you get will depend on tv stations in your area, up to about 100 miles away.
