I have come up with a few ways in protecting my antennas when in storage. Its important to protect the threaded stud on all antennas. Various vinyl caps and rubber chair leg caps can be purchased at your local hardware store. Got a coil antenna and need to take it off because your vehicle is being serviced on. Modifiy a pair of single serving Pringles cups. Cut a slit on the sides and insert a strip of velcro. Now the antenna does not roll around on a flat surface, Bulldog.
