Comet M-24M - VHF/UHF Dual Band Magnetic Mount Antenna - Ham Radio
Most mag mount antennas require you to pull the entire magnet and antenna of the vehicle for a car wash, secure it from theft, etc... This typically ends up scratching the mounting location. The Comet M-24x element is threaded onto the magnet. Simply unscrew the whip to lock it away or to allow clearance under parking structures, etc.

This simple mag mount dual-band antenna is excellent. I love the ability to accept up to 80 watts although the most I would push is 50 watts. Installation is quite simple and the magnet is very strong (don't slide it across your roof). I also like being able to unscrew the antenna from the magnet for those times when I need to remove the antenna instead of pulling the magnet off of the roof. You can't go wrong.
