I think and noted that when the vertical's near field overlaps with the
beverage, the coupling is noticeable and disruptive.
Of course the amount of detrimental effects are partly subjective, I mean
that if someone is accustomed to reception with poor antennas, or better to
say antenna s with poor directivity, the loss under investigation is not so
evident.
Who ever used a 2WL beverage in a clean environment for sure won't like what
happens having a vertical in close proximity.
