Unlike some other DTV converters, the AT-2016 has a smart antennae interface for use with a realtime signal optimizing smart antennae. Additionally its RF output can be set to channel three or four, unlike some other DTV converters that only output to channel three. Like most DTV converters, the AT-2016 has the ability to zoom in, and to letterbox, in order to better view 16:9 widescreen programs on a 4:3 TV. The AT-2016 however, can be hard to find.
