[VHFcontesting] Yagiphobia, Confusion and Infusion

[John Geiger]

If you stack 4 of those elements, and it is omnidirectional, then the gain 
has to come from somewhere. Where does it come from?  It would probably 
compress the take off angle, but in terms of beamwidth gain relative to a 
Yagi, it couldn't have any.

It wouldn't allow you to null out noise coming from a specific direction, 
which can be useful also.
