Review on 🔇 SING F LTD 10Pcs Noise Suppressor 7mm EMI RFI Clip Choke Ferrite Core Cable Filter by Jon Smith

Works well to prevent RFI on my RG6 HD antenna cables. I put mine behind the wall panels to hide them. The thickness of my rg6 wire is about 9mm and these fit 13mm a bit loose. It's not enough that they slip, but it could also be tighter. I don't know how they measure these filters at the factory, but it took me a second try to find the right ones.
