Why do some verticals have radials and some don't.

An in-depth discussion of ground radial and counterpoise systems from David Casler (KE0OG).

Dave does an excellent job of explaining the theory behind ground radial systems for vertical antennas. 

Not all vertical antennas require a counterpoise or an extensive radial system to function efficiently.

Dave examines several types of HF vertical antennas and describes the ground radial or counterpoise system best suited for those antennas.
