Yeah, those little magnets don't have the holding power of the larger ones.

I'm assuming you don't have an old car with a vinyl top, right?

About all you can do is either place it somewhere lower on the vehicle (probably won't help), get one with a larger base/stronger magnet, or switch to a permanent mount.
I guess some other options:
Place another large magnet on the underside of the sheet metal where this one is mounted.
Place it inside on a sheet of metal, but this'll reduce performance.
Duct tape!

You need at least a 3 inch diameter base to hold well on a moving vehicle. Those little toy antennae just don't cut it.

You could try it on the trunk on the passanger side to try to reduce the stress on it. That looks like too much antenna for the little base - especially with the coil. It's going to have a decent amount of wind resistance and capture area.

Maybe mount it on the rear deck (inside)...

Yeah, if you get the north/south thing right it works pretty well. Get it wrong and it's got the opposite effect.

Heck of a lot easier to just drill a hole and mount a proper antenna, but to each his own.

I have glued/epoxy those antennas to strips of metal, and then nylon cable tied the assembly to roof racks before.

Barring a roof rack, larger magnets could be put onto the strip of metal.

That weak magnet antenna is included with many devices these days, and do not hold well on anything.
