Here is the analysis report:

It's an old antenna, probably 20+ years old. But it has worked like a champ until recently. We live in south central Wisconsin. Until the recenly we could pull in stations from Milwaukee, Rockford, and Madison. Once in a while I could even get Channel 5 from Chicago. Money is tight, so I don't want to replace more than I absolutely need too.
I don't know a lot about the analysis. I apologize for not educating myself first. But I just happened to notice that the two channels I can still get are VHF-HI. And the preamp seems like a easy to replace part, out side of climping upon the roof
Thanks!
