Topband: 1/2 wave inv L

[Roger Kennedy]

Many years ago, a friend of mine used to operate on 160m with vertical
antennas suspended on a big Weather Balloon filled with hydrogen . . . 

After using Quarter-wave verticals for a few months, he changed over to
Half-wave verticals . . . he found they worked much better !

He didn't have much of a radial system (due to lack of space), mainly just
earth rods at the base . . . so I suspect that's one of the reasons why.
