This Zenith brand name box that is marketed by LG Electronics is the one that is my personal preference of all of the DTV boxes that I have installed or used. There will still be some low power TV stations that will continue to transmit on the analog channels as always in some areas. As you probably already know when most of the analog channels are turned off in February 09. When you turn off the converter box that has the “Analog Pass Through” feature, you can now view your analog channels as you always have with the analog tuner that is built into the TV set. If you are considering your first DTV converter or if you have never used one, this means that all of the digital channels that come through your converter box would be viewed on your channel 3 or you can select channel 4 if that is your preference. Analog pass through makes the installation much easier if you want both analog and digital capability, even if you do not need both you may later. You can do that without having to flip any switches or change any wires to go from digital stations to analog stations and back. Analog pass through will allow the viewer to see the low power repeater stations that are not going to change to digital. The Zenith DTT901 digital to analog tuner or converter, is as far as I know the same as the DTT900 other than the 901 also has the analog pass through feature.
