ECN Forum Forums General Topics of the Trade General Discussion Area snake oil?

There's none in my immediate neighborhood. I did try parking my car under one, and listened between stations on the AM radio, I didn't hear any RFI. And with many thousands in the county, if they did make noise, I may be awash in RFI. So they may be pretty quiet.

I think your typical inverter is about 15-20kz. I know my dog goes nuts around them so there is an audible component.

Looks like a classic sales scam to me. Overprices junk with a janky sales page / video.

I would avoid this at all costs or, more to the point, lack thereof.
