Not defending this at all but... there shouldn't be any, or close to no attenuation. It's a short length of high quality coax. Since they claim it's built to customer specifications, and they don't quote any, maybe the photo shows how it would be built, not an actual balun.

be allowed? I'm no expert but I've made a few chokes and never managed to
accomplish this kind of choking impedance with a couple of turns of coax
through a few toroids. Can someone explain please! Thanks
