For VHF, they all suck equally. Some might suck better (worse?) than others, but they all suck.
I haven't see any of the major antenna manufacturers make a "dual band" phantom style antenna, but I know some of the Cheap Chinese Antenna manufactures (located right next door to the CCR factories!) do.
Trying to squeeze 19" of radiating element into 2 inches doesn't work. Yeah, you can make it resonate on a VHF frequency, but you can do that with a dummy load, too.
What I can tell you about the VHF side of these things:
I know a few people that have tried these VHF phantom/low profile/shot glass/soup can, etc antennas.
All of them. Every single person that I know who has tried one, has regretted it. In fact I've had several people offer me used ones for free, that's how much they value these things.
- they are -very- narrow bandwidth, like 1MHz, maybe a bit less. Not going to cover the entire 2 meter band. That is IF they are tunable. Some of the Chinese ones aren't.
- they don't handle much power. 50 watts max. Anything more and they overheat (kind of like a dummy load).
- they are poor performers. Less than 0 gain (kind of like a dummy load).
Where they do work:
If you've got one frequency or a few that are very closely spaced. If you are within spitting distance of the repeater.
Honestly, it would be cheaper to just by a 50Ω dummy load and mount it on your roof. It would work as well.
On UHF they work a bit better. Cramming 6" of radiator into a 2" tube isn't quite as sucky. As you know, they work pretty well on 700-800MHz since it's not a stretch to put 1/4 wave inside the antenna and make it work. In fact, I have one and it actually works better than 1/4 wave.
But, if you've got to have one, at least let us know what you discover.
