[Antennaware] Radial mats under dipole

With respect to the folded dipole... For 160m stations at any real
distance the 33m vertical and 40 radials will vastly outperform an
inverted vee at only ~ 1/8 wave height. W8JI has tested a dipole at
more than 1/2 wave height. Even at that height, where a dipole starts
to perform well for DX, he does not report it as superior to his
vertical antennas.

At 1/8 wave, the antenna will be a cloud burner, directing the vast
majority of it's energy straight up. If that's what you want then have
at it.

73, Guy.
