Hey Charlie,
I have a few of them. One in my truck has about 200,000 miles on it,
from a few Ford Explorers...
It seems to tune well. My antenas are typically bug catchers but also
have one in my Chrysler LXI minivan. A great little tuner. I would
also look at the MFJ, but I have not personally seen or tried it.
