Hi Richard:
ClearStream Juice and Televes both have excellent reputations. Televes seems to be the most progressive in OTA technology at the moment, according to user reviews across the Net. The RCA Preamp you're using have tended to have quality control issues over the years. Sometimes they work fine, other times not so good. It's a known issue on TV Fool.
You might want to look at this while you're at it:

Highly recommended from users here at TV Fool over the past several years. I have not used their preamps, because I don't need one in my strong signal area. But I don't think you could wrong according to reviews here on this forum.
Let us know how you come out. I know it would be helpful to others.
All the best.....
