I use a fence as part of the ground system for my shunt-fed tower on 160 m.
What I notice most is that there is much less difference in the tuning in dry
vs wet soil conditions. I interpret that as indicating the fence has a positive
effect. My fencing had a black paint applied (that wears off quickly). I've
measured continuity from end to end so there are no breaks. I have no A-B
before and after signal measurements. If the fencing is truly insulated, such
that there's no end-to-end continuity, it may not work as well.
