Topband: Two wire Beverage Question

Of course it is too long.  Beverage said that when it is too long 
there are so many lobes (and therefore nulls) that it is 50-50 that a 
given direction will not be covered; that velocity factor may 
antiphase a given frequency at the transformer; that the extra lobes 
pick up more QRM/QRN;  that "for amateur purposes" (not 
point-to-point) one wavelength or so is optimum; if you don't know the 
exact direction the signal will come from then with more wavelengths 
of wire you are in the lap of the gods and Murphy, so sometimes it 
will serve your purpose and sometimes it will not.
