I ran a UHF glass mount Larsen antenna (KG-450?) for a while on my wife's old car. For single band use, and knowing the limitations, it performed as I expected. No issues with the mounting.
Mounting is all about the preparation. Glass needs to be cleaned with isopropyl alcohol first.
Some metal film window tinting (factory type) will not cooperate with through glass coupling. Defroster wires can cause issues, also.
Getting the antenna off the window when I was done with it was difficult, and I was honestly worried about damaging the glass.
But a multiband glass mount antenna is going to be a pain. They are half wave by design (or should be) and will be quite long on VHF High frequencies.
If you are looking for an easy installation, tell us what kind of vehicle you have and we could make some recommendations.
As always, permanent mount NMO in the center of the vehicle roof is going to be the benchmark for performance. I know it's a hard decision for some to make, but once you do it, you never go back.
