If that's the case, they were clumsy on their website because it clearly
states dBd.

Sounds like they're specifying gain relative to isotropic, hence an
extra 2.1 dB.

I have modeled some OptiBeam antennas and the published specs seem
accurate.
Of course getting 2db more gain from the same boom length would
circumvent
the laws of physics. I recently installed a 4el 40m OptiBeam on my
tower,
the SP6GXP version is 37% lighter.

His 16 element 20/15/10 tribander looks like an almost complete copy of
my Optibeam OB16-3, except that SP6GXP claims about 2 db more gain on
each band and uses lighter weight materials.
