Topband: Effect of trees

[ZR]

Its been shown on here and elsewhere, by many and many times, that once 
beyond a modest radial field the field strength goes up marginally to the 
classic 128.
Ive stressed many times that a mesh screen out from the base 50' or so for 
160 does more for the signal than going from 32-64 or 64 to 128 radials. It 
also stabilizes the all important maximum current area so that climate 
doesnt have much effect.
