Default 20 dB gain on 20 meters?!?

Well, if i am not mistaken, in order to gain another 3 db, he would
have to setup another similar array. That would be twelve stepirs.
Then for another 3 db, he would have to add yet another twelve
stepirs.

The second three steppirs only gained him 3 db over the first three
and the second steppir only gained him 3 db over the first one.

so, what does that three db mean?

Yeah, I especially question the practicality of going from 4 antennas to 6.
It picked him up less than 2 db, but doubled the physical size of the
array - same width, twice as high.
