No, I haven't used one of those, and here's why I wouldn't….
A 1/4 wave antenna is a reasonable size antenna for VHF and UHF, and they work well. When they start getting crammed into smaller and smaller packages, they lose a LOT of efficiency.
On UHF, 1/4 wave is about 6 inches, depending where you are in the band. Stuffing 6 inches of antenna into a 3 inch tall can isn't going to work well, but it'll likely be "good enough" for short range use.
On VHF, 1/4 wave is about 18-19 inches, depending where your are in the band. Now, imagine trying to jam 19 inches of antenna into a 3" tall space. It won't work well.
I know a few people that have tried name brand "low profile" antennas, and here's their experiences:
UHF: they work well enough. Not great performers, but a good trade off between size and performance. Like I said above, putting a UHF antenna into 3 inch tall can is doable, as long as you don't expect miracles.
VHF: Everyone, and I do mean -everyone- that I know who has used one of the "low profile" VHF antennas has hated it. I think a week was the longest anyone lasted with one of them. I've been offered several of them for free, because it was either that or they'd take up valuable room in the dumpster. Seriously. I don't know anyone that is happy with those antennas. They are -very- narrow banded, maybe you'd be able to get 1MHz of acceptable VSWR out of the antenna. The other drawback is that if you run much more than about 50 watts, they start to melt. Yes, melt. All that RF energy being put onto a small circuit board trace doesn't work well. Something has to give.
Where the VHF do work is if you are limited to only one or a few closely spaced frequencies, run low power, and only want to talk short distances. Then, they work, but will never work as well as a "real" antenna.
Basically what these antennas are is a circuit board with a bunch of traces on it that look like a 1/4 wave antenna on VHF and on UHF. The traces just run back and forth on the circuit board to make it fit into the small space.
While the advertising will claim a lot, I doubt it's true. I'd love to waste some money, but one, and put it on my analyzer to see how they look.
Seriously, unless you really have to have that specific antenna and don't expect much performance or range, you can easily do better. And for about the same price.
A 1/4 wave antenna is going to work very well. Even at VHF, it's going to be less than 19 inches tall. The whip material is thin enough that they barely show up. And, they are cheap. You can easily find VHF 1/4 wave NMO whips for $10 or less, even brand new ones from reputable companies.
…and what about UHF?
Well, a 3/4 wave UHF antenna is nearly identical in length to a 1/4 wave VHF antenna. In fact, I ran a 1/4 wave VHF (19 inches tall) NMO antenna on my old truck for years connected to a dual band radio. VSWR was low on 2 meters, like 1.3:1 across the band. VSWR on UHF was even lower. The trade off is that the radiation patter on UHF is a bit funky, but it still worked well enough for me. Primary use was on VHF.
You can get dual band whips for a bit more money. They'll work the same as a 1/4 wave on VHF and a co-linear on UHF. You can also get higher gain antennas that will work well.
Personally, even for 4 weeks of use a year, I'd go with either a 1/4 wave VHF antenna, or get a "real" dual band whip antenna. It'll work way better.
Antennas are ruled by the laws of physics, and no one, not even the cheap Chinese manufacturers, have a bottle of magic pixy dust that will allow them to cheat those laws.
I think you'd be disappointed with that antenna.
