YSHIELD has a great product, it's not cheap but it's very effective at eliminating radio interference. RFI is a problem almost everywhere in the city as there are towers and Wi-Fi everywhere. Our home is within 600 feet of one tower, two blocks from another, and three blocks from a third. It almost seems to be the norm. Then there's our neighbor's WiFi, which works very well when I'm using my EMFields AM-10. Plan to double prime the Yshield before painting as black is a bit more difficult to mask with lighter colors like white. Two layers really improve cushioning, and it's important to be mindful of areas where RFI can penetrate.
