I just hooked up a new antenna to an old analog T.V. through an RF Modulator. What are possible reasons I'm not receiving any signal at all?

Question

The VCR/DVD Player is also hooked up to it and works great. I'm just having problems with the antenna.

Answer 1

You will need a DTV tuner,
and I think you should also find a local expert who can help you in person.

Answer 2

TV broadcast changed from analog to digital some years ago, so the antenna pass-through feeds the over the air signal to your old TV the same as if you connected the antenna to the TV directly without the modulator. Your TV is not capable of digital reception. the modulator converts the VCR or DVD playback because composite video is analog. so your modulator generates an analog TV signal for your TV set which it can receive.
