Television programming in the United States went completely digital in 2009. Any analog set was rendered useless without a digital converter. Any new TV sets made since 2009 have to be set up for digital reception, but, a person with no cable or satellite service does need to buy and connect a digital converter to get an analog set to work.
Place the digital converter underneath or near the analog TV. Unplug both devices.
Unplug the coaxial antenna wire from the analog's "In" port.
Plug the antenna wire into the "In" port on the converter box.
Plug one end of the coaxial wire that comes with the box into the "Out to TV" port on the converter box. Plug the other end into the "Antenna In" port on the TV.
Plug both machines in and turn them on. Tune the TV to channel 3 or 4. Use the remote connected to the converter box.
