Have you ever heard of a shielding product that would clamp on to
existing utility service lines? I'm interested in shielding the service
lines from PECO that run in a T shape on my small city lot. Ideally
there would be EMT that could clamp on to them, like how the hot water
copper pipe insulation works.
I guess I could cut emt into half and then fit them back together. It'd
need to be fairly light.
Another crazy option is to use a metal conducting paint and paint the
power lines. There are paints designed for RFI shielding. I could
spray them, but it'd be hard to get full coverage.
This might be a crazy idea, but it is more likely to work than me
putting up $200 of ferrites on the power lines - as I don't have any
slack in them and would have to use the monster choke clamps. The
ferrites might help a bit, but possibly only 1-2 db - whereas with a
better shield I should get a 10+ db reduction.
The downside is that I'd need some 20 foot step ladders to do this,
whereas with the ferrites I can just place them at two points (on both
sides of my property).
I could track down the noise sources in my neighborhood. But there are a
lot of them, and with a high turnover of renters every year - it'd be an
