The dB reference was for a dipole mounted at exactly the same point as 
the beam.  The result is particularly useful, because "ground gain" 
(that is, the addition of the ground reflection to the direct signal) is 
cancelled out.

I see this as a particularly useful way to present the data -- that is, 
it answers the question,  "if I replace my dipole with X beam, how much 
louder will I be?"  And they also answer the question, "how does X beam 
compare with Y beam under the same conditions?"
