If you have an old analog TV, this device will allow you to watch a multitude of broadcast digital TV channels. In some markets you will be able to see upwards of 40-60 over the air channels....all free! You will need a TV antenna(not included). The device comes with a power supply and remote control. Enjoy an easy transition from analog to digital TV broadcasts with the Sansonic FT-300A Digital Converter Box, which enables an older TV not connected to cable or satellite to receive and display digital TV programming (ATSC). It supports programming and system information in both 4:3 (standard definition) and 16:9 (widescreen, digital) aspect ratios to fit any TV. It also includes a remote control that features mute, sleep, and V-Chip controls.
