[Antennas] RE: Strange Antenna ?????

Others have spoken to the reason and advantage of this method so I will 
only add that in my younger days, the old timers referred to this type 
of construction as a "birdcage antenna" and was used to make verticals 
for low band usage for the same reason. Like a Windom or Zepp, its name 
conveyed an image rather than exactness such as a G5RV.
