[RFI] Electric Fence pulsing (will get worse soon !)

Thu Jul 9 20:52:35 EDT 2015

He may be an expert, but I've seen cattle repeatedly test a fence and 
get poked every time.  If you ever lose power once, they quickly learn 
that fence isn't always hot.  That will imprint over all the training.
Single nail,  good ceramic insulators are not power robbing, RFI 
generators.  At least they weren't 35 years ago.
