What is the Best 4x4 antenna?

On my rigs I tend to run 1/4 wave antennas on the roof unless it’s a soft top where that just isn’t practical (then I run a 1/2 wave antenna on the driver’s side fender) for VHF/UHF applications. I’ve found it’s just really hard to beat the functionality and simplicity of a 1/4 wave antenna in most real world mobile applications. They are cheap, typically $10 or less for a name brand Laird or Larsen, and depending on the terrain are more effective.

On my Cherokee I run a Larsen NMOQB with spring for VHF on the roof. It’s been there for 10 years now, drags going in and out of the garage, I hit it on things quite often, never have had a problem with it. On the same Cherokee I also run a Larsen NMO27B for CB on the fender. No spring, never have had a problem.
