Larsen used to sell two versions of a dual band short antenna.
NMO-2-70SH and I don't recall the other one.
One was a closed coil with a spring base. 1/4 wave on VHF, so about 19" tall. Base and coil were black, whip elements were chrome, but it's easy enough to put some heat shrink on them.
Other one was an open coil with no spring. Also 1/4 wave on VHF. It was all black.
I own both and they both worked well.
However, keep in mind that a 1/4 wave VHF antenna is an odd wavelength on 70cm, so they actually work quite well. I did this for years on one of my trucks. A simple $10 1/4 wave VHF NMO antenna. It probably had an odd radiation pattern on UHF, but I never had any issues with it. Checking SWR showed the SWR was actually better on UHF than it was on VHF.
And, very low profile. A thin whip chrome 1/4 wave antenna really blends in well. You can also get the whips/base in black, or just do the heat shrink trick above.
