Barbed wires fence under power transmission line...

[Externet]

What is a better approach to harvest some radiated field from barbed wire parallel to an overhead high power transmission line ? :
-A bridge rectifier at one end of a barbed wire against a grounded rod, or
-A 60Hz LC tuned circuit from the barbed wire serving as antenna against a grounded rod. (plus rectification)
-Or other ?
And why?
Not interested in legalities.

As the wavelength at 60 HZ is 50 X 10^6 m, it is unlikely that you will have any aerial pickup, only a capacitive pickup. this means that you can get lots of voltage but you will not be able to get any current out of it.
