V Beam, do they work?

It looks like a simple antenna, has a good reputation, but it doesn't
look very useful for anything. Unless there is a combination I'm
missing.

I've never worked with a Vee antenna. But, while stationed at Hill AFB,
Utah we used two of them back to back to make a Rhombic :-) to support
the South East Asia phone patch nets during the Vietnam conflict. Fixed
point to point communication [We had an LP that was used for stateside
COMMs]
My understanding is that a narrow beam is formed along the axis
[centerline] of the Vee. In a standing wave antenna, the beam is
bi-directional. In a terminated antenna, traveling wave, the pattern is
unidirectional. The narrow beam width reduces interference from
undesired directions.
Total wavelength and included angle have significant impact on performance.
I wonder of Roy can add constructively to this discussion regarding
apparent low gain.
