Installing 60 33ft radials is definitely not necessary. From the real
estate listing it looks like you have plenty of room in your backyard for
ground radials. They do not need to be any particular length or in all
directions, just put in what you can the best that you can. The SteppIR
vertical will work OK and you won't have a maze of elevated wires ruining
your yard.

I have a SteppIR BigIR vertical that I am refurbishing. It will be
installed
in a small backyard that does not allow for the normal ground radial system
(such as 60 ea at 33'). I will need to go to 2 ea tuned elevated radials
for
each band (80 thru 10 - 8 bands). My solution (I think the only one I have
due
to lot restrictions) is to run the radials along the vinyl fence. The
vertical
is mounted on a 4x4 post at 5 feet above the ground. One direction has
about
70' of length (straight) but the other direction has a 90-degree turn about
20
feet down from the antenna and then a straight shot the rest of the lengths
so
the radials for 80, 40, and 30 will have a 90-degree bend at that point and
then continue on straight. All the radials will follow the fence line so
they
will not be spaced out is a circular distribution from the antenna. There
will
be about 1 to 2 feet of horizonal spacing in the plane for 4 bands (80, 40,
30
and 20). I will do a similar install for the 17, 15, 12
and 10m bands but will have them be 1 to 2 feet down vertically from the
1st
set of radials. Hopefully, this is clear and not confusing - I do not think
I
am able to post a diagram of what I want to try.
Couple of questions:
Will this work?
What is the minimum spacing horizontally and vertically for the radials as
proposed?
Any other suggestions?
Thanks,
Dale
