Thanks Arizona & Hikerdogs, The previous owner did leave the converter box, today I will try the antenna. We have a booster for the antenna signal but when we're at home (we live in the foothills about 40 miles out of Fresno going towards Yosemite) it may not help with the trees and hills.
I was going to see if I can use the receiver box from DirecTV that we have in the house for the SAT., finally found the connections in the left hand overhead cabinet.
The trees may not let the signal through there either.
Anyway, thanks for all the great advice and help. I can't tell you how much this site has helped us.
Thanks again and safe driving,
MT
