Thanks so much for all the feedback. If I could ask another question,
which antenna configuration do you think I will have the most success
with, the dipole in the attic or the trimmed Radio Shack CB antenna?

Where is the CB antenna, and what do you have it stuck to? How long is it?

Chances are pretty good that the CB antenna is a serious comprimise. I
think you'll probably find the attic dipole a better performer.
