I had once used stranded wire inside teflon insulation and had the 
same symptoms and the cause was exactly as you conjured. The 
wire was broken inside the insulated wire. The reason it happened, I 
finally observed, were squirrels would "sample" the wire and the tell-
tale sign were very tiny nicks in that tough insulation. On my 60' x 
90' lot I use tall pine trees to support the antenna. I changed to a 
much heavry gauge wire and spaced it from the trees. Maybe this 
will give you ideas if you have the errant roadent chewing on stuff.
