This antenna was just released to us and provides truckers and RV owners with a much better alternative to the standard car antenna.

This antenna is designed to be installed on the mirrors long-haul trucks and RV's to provide the best of reception.

I've taped a small magnetic car antenna to the truck mirror for years. I finally got fed up with dead spots and purchased the truck antenna. Naturally, it receives much better.
These manufacturers need to come up with an alternative mounting design. Fewer trucks have the metal tube type mirror brackets. Newer trucks have a single pedestal/arm mount. For this price, we should not have to jerry rig something to adapt.
I would like to know why I can get more than 100 feet into a tunnel and have continuous reception, but underpass a 2 lane road and there is a break in reception. Same performance, car or truck antenna.
