I have a Zenith TV that's very similar to this TV except my Zenith has a 75 Ohm input already built into the set and it has a digital readout on the front panel that's 125 channel capable (Cable and regular Antenna) but my TV also uses a jumper for the antenna but whats weird is that the TV doesn't have a built in antenna but it has a jumper for one and it has a hole on top of the TV for an antenna to be inserted (using Zenith's proprietary half inch antenna mount hole as opposed to the usual quarter inch antenna mount hole) but there was no antenna with the set when I got it.
