[TowerTalk] Overlapping radial fields

[Rudy Bakalov]

 I have a similar question- I am going to bury radials for shunt feeding the tower on 160 and for the 80 4SQ around the tower. Do I need to have separate radials or the radials can be shared between the two antennas? According to the literature once the number of radials exceeds 32 the radials become non-resonant and thus my thinking it may be possible to share the radials.

 Can anyone refer me to articles in journals that discuss the performance of
quarter wave verticals installed with quarter wave radials that overlap?
Have not located anything in my “library” of publications about this
subject.  My station has both the 80 meter and 160 meter antennas sharing
the same radial space for about one third of the radial field.  Both
antennas have 60 quarter wave radials for each band and subjective results
have been very good.  Would like to read about any compromises in
performance caused by the overlap.

Both antennas have the expected VSWR and are fed through a ferrite balun.
