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
