Another good book ... Low Band Dxing by ON4UN ...
Lots of great info to defuse some of the popular ham lore ...

Be careful ... here ... there's more than one variable to consider. Raising
the feedpoint on a 1/4 w vertical may change it's impedance ...

The KB8I work has been debated for many years now. W8JI/ON4UN/and
a "7" station did some real world comparisons. Th NEC models are
off by about 6 dB ... so some, that matters not, to most, it matters much.
