I had a look at the referenced website which claimed up to 4db gain in
several directions but NEVER 12 db gain over a dipole. Now here I realise it
comes down to semantics. 12db gain over the ENDS of a dipole. Yes. 12db gain
over a dipole lying on the back lawn. Perhaps. 12db gain over a similarly
installed height, rotatable dipole. No way in Hades.

It's a lot for a 40m end fed dipole which, by the way, is what I am using on
6m at present.

Funny: try as hard as I can,with EZNEC, can come up with
4.12 dBD gain, and a f/b ratio of 1.44 dB (in free
space), and at 20 ft elevation, has about .1 dB gain
over the free space amount from ground reflections!
Does this mean that EZNEC has a BUG ??
I don't think so! And, at the price-
could double the amount and get a antenna with REAL gain!
As for me , I'll stick with my 7 El M2, with "only" 10.5
dBd gain ! I'd like to see the field, and equipment that
was used to measure that 12 dBd gain-- I don't think so!

This is a great working antenna, with 12dB
measured gain over a dipole. It isnt a beam, but
it sure is better than a dipole!
