These things are pretty amazing. Very cheap, they are a 3 port device which basically works like a diode, but for AC. For example, it let's a signal pass from coaxial connector A to coaxial connector B but not B to A. There is also a third coaxial port C which passes C to B but not C>A or B>C. So they can protect a main cable from faults on a drop C. They are small passive things maybe an inch square. They are very broad band but do not pass DC. This is powerful magic. thanks
