[TowerTalk] Elevated & Ground radials

[WD4K]

The question is: In an 80m 4 sq if three verticals  NE,NW,SE are within an
inch of each other at ground level and the 4th vertical has to be placed on
a severe slope...as in 8 feet or more...then what is the best setup for this
SW vertical....ground radials or a configuration of elevated radials for
this one vertical?
Understood about one vertical, ground or elevated...not a prob...but when
figured into the 4 sq system...another set of issues crop up.  Ideas???
Thanks, Tommy WD4K
PS This is a real deal, all is built. verticals =aluminum 2 1/8, 48' tall,
supports are in concrete, k4SQR system... and all is ready to go up other
than the SW vertical raising system and the complete radial system...the
manual part is easy...it is the design and interaction I am concerned
about....all help and suggestions welcome!! Tnx
