Ferrite gadgets - beads, etc.
Friends -
I have a few queries regarding people's experience with Ferrite, esp. beads and so forth. Can these things actually reduce noise? I see them suggested for encircling coax cable, electrical wires on appliances and electronics, and many other devices. If one were to put them around a coax cable, how many would one use in a row? I have also seen suggestions that ferrite cores with the offending wires wound through them are useful as well - how do these compare to beads? If one wound a wire around a ferrite rod, would this also have a similar effect? I presently use an A-D DX-Ultra, have used random wires, and intend to put up some more wire including a new random wire and probably a loop encircling most of my property along the fence and roof eaves. I expect to feed these wires using coax with matching tranformers. The radio and accessories are grounded, which clearly increases both the signal and external noise. I appreciate any and all answers. The noise in my neighborhood, mostly the result of artificial external problems, is really discouraging, and if these things would help even a few dB, it would be a blessing. Many thanks, Bruce Jensen |
