Andy is correct, its NOT a case of the lower the better for NVIS.
That's only true if you have a copper plated back garden and can cope
with very low feedpoint impedance. Modelling suggests that the optimum
for NVIS is about 1/4 wave high. If you go lower then ground losses
start to outweigh theoretical NVIS gain.
