I have a TV antenna I put in my garage attic. It is aimed the correct direction, but the reception is quite poor. I assume this is because it is mounted indoors.

I bought the largest model I could find, but I get fuzzy pictures on the UHF channels that are 20 miles away. The local Fox channel is a LP station 25-30 miles away and I can't get it at all.

My question is, do these amplifiers that are availiable actually work, or would I be throwing my money away? Money is tight right now and I don't want to spend $60+ if it's not going to work.

Also, does anyone recomennd any particular type and model over another?
