What's all this stuff about resonant antennas? Some great antenna designs
do
not use a resonant length.


All antenna 'systems' are resonant because they all present a resistive load
to the transmitter. QED.

I suppose I am being picky Reg but shouldn't resonance be defined as
"totally" resistive load. An antenna can only be 'resonant' at one
point or frequency because movement from this point collects
reactance.
Fortunately it still has a 'resistive' component load which is the
PRIME requisite for radiation, whereas 'resonance' is not.
With the above being fully understood by newcomers a lot of the
mystery about 'antennas' and 'antenna systems' falls aside.
