[Antennas] Q loaded versus unloaded

[Hue Miller]

Has this been already discussed here?
What kind of figures for Q would you typically get for
a wire antenna without any loading?  For example,
a one-wavelength antenna would act like a high-z
tuned parallel resonant circuit. Assuming wire size
is large enuff so ohmic resistance isn't a substantial
factor, what might be a typical ballpark figure Q?

Would proximity to ground affect this "Q"? If so, which
way? In other words, would a dipole at lower wavelength
above ground have narrower or broader bandwidth?

Also, forgive a dumb question, but where can i find
the formula to calculate impedance along a wire, in 
one of the  ARRL or other books?
Okay to just point me to a good but not extremely 
mathematical book. Probably not an EE text.
Thanks-
