Most roof antennas have a wall plate/amplifier that must be turned on for the antenna to operate correctly. (push button on wall plate)

Also, most newer TV's require you run a channel scan to auto tune to the stations available.
You will need to do this each time as you move about the area as 'over the air' channels change from location to location.
