Eric,
Years ago, at the K2GL contest site in Tuxedo Park, NY there was a similar
situation for many of the towers. They were put on pier pins and guyed.
Then a huge fan-out of radials was spread across the hillsides on the side
from many of the towers.
Years after the site had been sold, I helped take down several of the towers
and we found much of this wire in place and in good shape.
Thanks & 73,

Subject: [TowerTalk] Self-support Tower on Rock?
TT Gang,
We have been considering moving from our little in town lot to the country
side. One of the homes on our short list has about 2 acres of land but there
is only a scant few inches of dirt and in some places no cover at all over
top of what I can only call fractured rock. To me it looks like good old
limestone and by fractured I mean it has small crevices that go into the
ground every so often, with areas about, let say about the size of car
parking spaces.
To be honest, as of yet I have not checked with any tower manufacture or
dealer yet, this will come too. I do however wish to ask those that have
firsthand experience erecting self-support towers on rock, that would be
both advantages and disadvantages. The main disadvantage I see is these is
no simple way to install a ground system nor do I see a easy way to bury
feed lines and control cables in the ground without.
Though there is plenty of room for guyed towers I really would like to stay
with self support. My one tower is a Trylon 72 ft which I was hoping to
recycle at any new QTH we might move too and I remember Trylon having
options for rock, just not sure how well they work. I have not decided if I
will recycle my older Delhi second tower - yet.
All ideas welcome?
