# How does a multi-element vertical work?

For example, Diamond makes the X700HNA which is stated as a 4x5/8 vertical on 2m. Does this just mean that it is 20/8 wavelength long vertical? Or is there some magic to phasing the 5/8 segments? I'm familiar with colinear dipoles, but they normally have some sort of phasing connector (typically looks like a "hairpin" in my experience). Maybe that's just hidden inside the fiberglass, but I'd be curious if anyone has any idea what might be inside an antenna like this.
