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.

Hi Ken and all ,

Great comments,  All I know at this point is most of the 3-4 part fencing is
very new.  The original section 1000' away I don't think I ever heard, or if
I did, it was really weak.
He's adding sections all the time, but you're right....I don't think the
section that runs literally 20' from my antennas is online yet. I am sure I
would felt a slight shock.....even with sneakers on.

All I know about his controller so far is that it's battery operated, solar
charged and has 2 short-ish ground rods.   I've never been over to his land,
preferring to talk to him casually on our property line a couple times,
allow him some time to tweak his grounds and other connections we discussed
and put the last section , closest to me, online. He's promised to look at
it and is a smart guy 'cuz when we talked grounds, he knew right away he
didn't have enough of one.

I'd rather not be a mosquito (hi hi_) even though he doesn't really realize
the noise and grief he's causing me, I think it's tactically better to wait
til it's all up and running then perhaps I can help him fix whatever issues
exist at that time, rather than visiting him a bunch of times. (I'll become
that pesky guy he won't want to listen to, I am sure.....BTDT)

Good info on the Clydesdales.  We're looking forward to seeing them 75-80'
from our back window.  For 11 years we've looked out onto an empty cow field
surrounded by boring, thick woods.

  I tried touching it with the back of my hand (gingerly!) but was
wearing sneakers, standing on thick grass and nothing, nada, zip,
zilch, not a tingle.
That tells ME, flatly, that it is NOT working. You most certainly should
have felt at least a "tingle".

  I tried putting an AM radio up there and can hear it, but it's no
louder 10' away than it is 1" away from the wire-rope.
Then it is NOT working.

My neighbour put the rope down through the split in a large plastic
coated eyebolt type of insulator, but then proceeded to put a wrap and
a half VERRRRY tightly around what I would call the shank of the
plastic coated eyebolt making it so the wire was maybe 3/8ths-1/2"
away from the new cedar post he was mounting the ropes on. The shank
has little platters/Frisbees on it, much like a dipole egg insulator.
Whether he thought it, or someone told him, I envision he just thought
they were to hold rope.

No. They are NOT. They are insulators.

  The rope is really close to
new 4' cedar posts now.  I think a toddler would be able to do a Nick
Wallenda across these 6 acres of ropes.
The cedar posts would be a non-conductor, at least until it rains.

I thought rope type 'floated'?  I don't wish to pee off my neighbour
by challenging his install methods as I know sometimes you only get
one crack (two at the most) before neighbours run out of patience and
send you on your way and never allow you back on their land.
True. At this point, you are in a difficult position.

I firmly believe his installation methods totally suck, but proving it to
him, withOUT pissing him off is going to be.....um.....difficult?

I thought perhaps if I could somehow 'prove' to him his fence was
arcing or otherwise not providing much voltage (losing it all through
the very close cedar posts and tall grass) my word would be worth more
and I would actually be HELPING him keep his expensive Clydesdales in.
Good idea. BTW, Clydesdales are wonderful horses. They are really the
"Gentle Giant" of the horse world. As an example, the veterinary medicine
school at a nearby college has one named Jack. Every year there is a sort of
celebration at a nearby park. The vet school brings him there, and kids
crawl all over him, hang on his legs, etc, with nary a snort from him. He
seems to enjoy all the attention. He is absolutely huge, BTW.

  Help him...help me.  I am
thinking of buying one of those multi-voltage HV fence testers and
seeing how much the voltage spikes were.
That sounds like a good idea. You may even be able to sell it to him after
he sees that it is a valuable means of keeping his fence in good condition.

  IE: If it showed 100v or 1000v, I could then demonstrate he's way way
below what would keep these giant horses in and would then perhaps
listen to my other suggestions.

Words of sage advice?
Do you have any idea of what make and model of controller he is using?
Finding that out, then doing some research, even calling the company, might
give you at least SOME ammunition.

I would be willing to bet that he is, essentially, shorting ALL his "juice"
to ground somewhere, and what you are hearing is an arc at one of those
points.
