Welcome to the forum oldgatefarm,
Let us know on that antenna, and any other detail you think that would help us out...
1. How well did you receive analog channels before connecting the converter box?
2. If you do not know the make/model of your antenna, is it located indoor or outdoor? What does it look like? Do you have to plug in a power cord to it?
3. Are there any obstacles that may block
dtv reception at your location?
