Ferrite rod choke balun
WebJun 18, 2015 · The 1:1 choke, built from a bifilar winding on a ferrite core, is a foundation component for a multi-core Guanella current balun. You see a lot of diagrams that show … WebHeres a neat 1:1 50 ohm balun for use on HF horizontal wire dipoles. It uses an AM radio ferrite rod, with 3×14 turns of wire. 10-14 turns should be good for 2-30MHz. I used 18SWG enammeled copper wire. It all fits in a …

WebAn RF choke can be used in place of a balun. If a coil is made using coaxial cable near to the feed point of a balanced antenna, then the RF current that flows on the outer surface of the coaxial cable can be attenuated. One way of doing this would be to pass the cable through a ferrite toroid.
