I have found that the low profiles work fine if you don't use your ac or your 12v roof fans. That said, I still have the original batwing that gets digital signals perfectly. I find myself using my hot spot more these days than my TV antenna.
I've been thinking about picking up one of the cellphone range extenders that mount on the roof, haven't done it yet through
Has any of you old radio jockies messed with trying to use your old CB antenna's for range extenders and such?
