That's the one I run, with the open coil in the middle. It's been a solid antenna. I have a 5/8λ single band VHF, the Larsen NMO150, around here somewhere, too. It's a taller than the 2/70, of course doesn't have the coil in the middle and the base is smaller. But the performance isn't much different. I use it in place of a 1/4λ super low profile whip on the roof when I'm not going through drive-thrus and garages.
