I can only get one channel using rca digital converter, an old tv & new antenna.

[TECHNOT1]

I have RCA digital TV converter + recorder, an old TV & a new antenna. I can only get channels 8-1 and 8-2. Both channels show up super clear, but one has old shows in black and white, which I like. BUT HELP!!!!

You are going to have to try different positions for your antenna. Higher is always better. If it directional you would try different directions.
After you move the antenna you have to run the channel scan again so the TV will program itself for any new channels. You might also need a different or better antenna.
