Thanks Joe - We had a huge ice storm not too long ago. It was great, no bad tv reception! Why do you think rain and ice take away the problem?

The arcing spark is creating radio noise, much like the brushes in electric motor. The ice/water probably acted like a short to bridge the gap. Eliminate the arcing and the noise should go away. That doesn't mean you don't still have an issue, but you can watch TV.

You said it stopped when it rained. I would think the water makes the conection to ground. Is the TV better when it rains. If yes make sure all metal on outside of your house is grounded.. This is very low voltage or you would have had dammage by now.

I wouldn't worry about how high the voltage is nearly as much as I would be worried about the amperage.

Call the electric company to come out and take a close look. No matter what, it's their problem. Whether it's coming from the electric lines above you or from your own meter. It's still coming from them.

They wouldn't like the publicity they would get from burning down your home.

It opened for me. I thought this was a pretty convincing paragraph:

WIRE FENCES Barbed wire and woven wire fences insulated from
ground on wood posts can assume an induced
voltage when located near power lines. If you are
having a shock-related problem, call BPA for an
investigation. The fence may need to be
grounded if:
it is located within the right-of-way;
it parallels the line within 125 feet of the outside
wire and is longer than 150 feet; or
it parallels the line 125 to 250 feet from the
outside wire and is longer than 6,000 feet.
These fences should be grounded at each end
and every 200 feet with a metal post driven at
least 2 feet into the ground.

Apparently people don't remember the days when people living near power lines wound copper wire on a wooden barrel and buried it in the ground under the wires to get free power. Eventually the power company found out where the "leak" was....

Yes, good read regarding BPA's regulations and services. They even come out and investigate and even ground the problem! Too bad they are in Oregon and I am in Tennessee. TVA (my local utility company) came out and scratched their asses. Looks like I will have to tackle this one on my own. Wish me luck!
