We purchased a new TV (i.e. digital) and it works fine with the original antenna equipment on our 1992 Classic. We simply crank the antenna up, use AntennaPoint.com on a smartphone to find the direction of the signals, then rotate the antenna to the appropriate angle (using a simple compass). After that we use the menu on the TV to scan for the channels in the area and we receive the local stations. Works fine for us.
In some locations, the broadcast signals come from varying directions. If the signals are weak, and the signals come from dramatically different directions you might have to rotate the antenna depending on the channel you want to watch. This situation is true for us about 50% of the time.
By the way, we use a similar approach at home - we have new digital TVs but we use an old-fashioned multi-element antenna and we receive all the channels in our area.
