In case anyone else has this issue, I found a fix that I haven't tried yet, but I've been told will work. I have a 48" firestik antenna and I turned the adjustable tip all the way down. It still needs to be shorter. I called the company and was told to take the tip off, remove the lock nut, and put the tip further down. If that doesn't work, take the tip off. I'll let everyone know how it goes.
