The AMD Quadcell Antenna is a different type of noise filter. The Antenna couples to RF and low band EM noise that is floating around your room. The Antenna does nothing to clean the A/C in the wall, but it draws in airborne noise floating around the room and routes the noise to earth (or Neutral in our case).
I bought three, one for HiFi, one for office, and one for bedroom because several people with high health sensitivity to RF said it really helped them. It worked well for my HiFi but not for my health symptoms, so I’m selling the two extra. (The biggest help on my health was getting rid of the DECT cordless phones and replacing with Siemens Gigaset with Eco Mode.) Included are plug adapters in order to handle the American plugs. Keep the hole for the Earth pin to the top of the unit.
You only want one QC Antenna for the room; think of it as a star ground to airborne noise. Place 1-3 metres from the HiFi components. Because it routes the noise to neautral/earth, it does help to have some additional treatment for mains noise, which treats neutral and/or earth. From Alan Maher: “You can play with the wall location a little bit when trying to blend with stereo / AV filtering vs. overall Antenna strength interaction. Don't go overboard with close proximity because analogue signals work at different frequency compared to digital signals...and what you don't want to do is a massive suppression because the filter is too close to your turntable which can cause a major suck out ...so if you notice too much top end roll off or suppression just move the Antenna an extra meter or two (up to 3m) from the stereo.”
