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...


Here's a quiz question: Suppose the dipole could be made fat enough to
reduce the resonant length to 0.01 wavelength. How much would the gain
be reduced?

Part 2: Suppose the dipole remained the same diameter and was reduced in
length to 0.01 wavelength. If the conductor were perfect, how much would
the gain be reduced?

Hint for Part 2: This is easily answered using the free EZNEC demo
program, another modeling program of your choice, or a few minutes'
reading of just about any antenna textbook.
