And since very few of us operate in free space, dipole gain varies all over the
scale dependent on hight above ground and the angle you want to measure the
“gain” at. I have recently seen where a dipole at the proper height has up
to 8 dbi gain (at the right height and at a desired angle).
In actuality, “gain” in a non rotatable antenna is a myth. OVERALL, an antenna
has no gain over an isotropic radiator, it just subtracts strength is one
direction and focuses it elsewhere. That’s good if “elsewhere” is the
direction you want to communicate, and not good if you want to communicate in
some other direction.
