Despite the obvious theory, and over 50 years in amateur radio, I still
find it hard to believe that, in real life, an 80m dipole at (say) 20'
ever really outperforms (at any distance) one at (say) 100'. Given the
choice, I know which one I would choose!
Try reading these:

Thanks, I'll certainly have a good read of those articles. But
regardless of what they say, in a typical amateur scenario, I still
reckon that at (say) 300 miles, an 80m signal from a dipole at 100' is
likely to be stronger than one from one at 20' (or even at 60').
