The antenna on my car is supposed to retract into the back of my car when the radio is not on, but it doesn't. As a result the antenna got a little bent, it was not a big deal. However, one day while parking near a friends house I drove under a low hanging tree and really bent the antenna. I knew that I had to act fast or loose the antenna entirely.
Duct tape to the rescue!!!
Duct tape and wooden shish kebob skewers.
There, I fixed it. Now the antenna is strong straight and I get better radio reception than I used to.
