This is a balun created by winding two separate wires around a magnetic core (the same as any transformer), and grounding one side of the primary winding.. 2022. 3. 11. · What is Toroid 3. 11. 2012. 7. 27. · Types Of Current Baluns l Multiple Winding Ferrites – Each pass through the center of a ferrite increases the impedance by the square of the passes – Multi-turn Impedance = 1 Pass Impedance x (No of Turns)2 Using graph on left - Z @ 4Mhz = 70 -. A balun's purpose is to allow connecting a balanced, (e.g., a dipole or driven element) to an unbalanced line such as coax which is not balanced, thus the name, Balun. The 1:1 choke "balun" is not actually a balun. It's function is to help eliminate rf currents from flowing on the outside of coaxial cable using the principle of choke action.
