Remember Frank that if you would use insulated wire and merely lay it on
the earth you may be able to take advantage of the velocity factor which
would shorten the need for a longer wire which is elevated. The closer
you wire is on top of the earth the more pronounced this effect should
be. It may also depend on the ground beneath the wire but some users
of this method claim that a 90' wire laying insulated on the ground
works as well as a full length quarter wave elevated one. Also you
might consider laying down a ground screen of 50' by 50' and measure
some base impedance before and after. Of course there may be no
advantage to using both as one may defeat the purpose of the other.
Again depending on the soil conditions, ground screens are said to be an
adequate alternative to full sized ground systems.

Hi all...
I do have vy limited Space here on the ground..
My Radialfield now is some 60 to 80 Radials between 5 and 20m....most? of them
below 10m? and they are some 2 to 3 cm in the ground..
I can do 3 Elevated Radials some 2m high with a leng of 30 to 40m.....to get
them in resonanz i can fix them with a ltle coil at the ends maybe...
Anny have experence can know whats a better solution?
