I have been reading these testimonials about how well short
beverages work. It depends on what you mean by "work".
They might be useful antennas, but whether they are
functioning as beverages is another matter. At least
at my QTH, a low (30 feet high) dipole is usually a better
receive antenna that a vertical. A low dipole is omnidirectional
as far as I can tell. A beverage that is working as a beverage
will exhibit very noticeable nulls. It would be interesting
to see if really short beverages exhibit these nulls. Otherwise,
useful as they may be, they are acting a degenerate low dipoles,
but still beat listening on the transmit antenna.
