[TowerTalk] Radial question

[Jim Brown]

That advice comes from N6LF, but it is sort of reinforced by the much 
earlier table of radial lengths from the ARRL Antenna Book. Loss in 
radials is greatest where current is greatest, and that's near the base 
of the antenna. Power loss is I squared R, and the greater the number of 
radials, the smaller the current. So using more short radials is better 
than a few longer ones, especially if they are on the ground. Also, 
there's nothing magic about 67 ft -- it's still much shorter than a 
quarter wave, which is in the range of 90-100 ft for a wire laying on/in 
the ground.
