Re: Topband: Necessity of a Ground Screen under a well radialed vertical

["Bill Tippett" <btippett@alum.mit.edu>]

Hi Doug,

Some would say even 120 radials is overkill.  I believe ON4UN says
about 0.025 wavelengths between 1/4 wavelength radial tips is adequate
to screen ground losses.  This is about 13' on 160 which means you
only need about 60 radials.  W8JI agrees with the 50-60 number based
on actual field strength measurements.  IMHO ground screens are a
waste given how close radials are at the tower base.
