I have used one like that the past 2 years, over a tree on 160. The end is
up in the air about 6 meters and nobody can touch it. I am using the old
W1BB style with a length of abt 52 meters and a series capacitor at the
feed point. Works quite well with a mixed bag of radials from 6 to 40
meters long about 2 meters above ground.
