its best to go with fence that has welded or brazed joints instead of just twisted or crossing wires. any place that can get corrosion or water in a joint is a place for rectification or sparking to happen.

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.
