I dont know where YOU got your antenna info from....but just because a
dipole has wide b/w (low Q) does not lower its gain unless the diameter of
the dipole causes the resonant length to be much shorter than 1/2
wavelength...but in practical terms, that wont happen (unless he makes the
dipole out of 4 ft pipe for instance!

A wide b/w (fat) dipole made for 80m (a cage dipole) does not have any less
signal strength than a single wire dipole (2.15 dbi).....sorry.

It`s a fact. Fat antennas have more bandwidth, and that is inversely
proportional to Q. Teducing antenna Q, by fattening the antenna, reduces
the antenna potential by about the same factor.
