Topband: NCC-1 Phaser

Probably....but that depends on where on the fence itself the actual 
voltage breakdown is taking place. The electric fence may propagate the 
noise like a long wire but you might get lucky with the NCC-1. I'm not 
sure but I believe the best to do in your circumstances is to use an 
antenna that picks up the noise the best, whatever that may be, to try 
to null against it.  If the noise if from some distance away you 
probably won't have that much luck.  In which case try to physically 
separate your EU RX antenna as far away from where you have located the 
noise and at a different angle toward Europe. Best to accurately pin 
point the exact noise source.  I have even heard where one ham designed 
a series tuned trap and put it from the wire to ground and tuned for a 
null in the 160 meter band.  I don't know about this but another choice 
is a remote controlled solar power relay for night time operation.  
(Probably not recommended in your part of the world.)
