Balun wire
웹2024년 3월 27일 · Baluns are commonly employed to obtain nearly balanced feed line currents (ie negligible common mode current) in two wire lines or negligible common mode current on coaxial feed lines. This article discusses baluns for that application. A very common 4:1 current balun is Guanella’s 4:1 current balun, but there are others including pretenders. http://www.jdunman.com/ww/AmateurRadio/Electronics/Test,%20measure%20balun,%20and%20compare%20antenna%20baluns%20or%20balums.htm
