What would be a good 6m antenna for the car? It needs to be either mag mount or lip mount for the trunk.
Is there an advantage to using the Larsen NMO-50 over the NMO-150 for 6m?
Sounds interesting. Does this antenna work reasonably well on 70cm?If you get the Larsen 5/8 2m NMO antenna it will work about the same as the antenna posted above as a resonant 1/4 wave with a good match and its also a 5/8 wave gain antenna for 2m.

And I think the fact that the NMO150 happens to work on 6m is because the coil (VHF matching section) isn't DC grounded. I've come across other VHF 5/8 wave antennas where this isn't the case.
2 meter and 70 CM are fine with VHF antennas because the are near a perfect 3:1 frequency.
6 meter doesn't multiply evenly so you get bad performance on 6 with any 2 meter antenna.
Likewise, an antenna tuned for 6 works poor on 2 and 70cm.
seeing is believing looking at a VNA.
I will put up screenshots when I get my puter talking to the VNA again.
