Key uses for the 1:1 current-balun: a) is to marginalize the “inverted-L current” in the transmission-line feeding a dipole-antenna. This will prevent a radiating Feedline and prevent distorting the antenna’s radiation pattern. There will be some flux in the core but it’ll be minor due to the small ...
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. 웹기존에 저희가 만들던 하이 파워 발룬(BASICOMM Balun)에 비해 가볍게 만들었고, 주로 와이어 안테나에 사용하기 편한 형태로 개발 했습니다. 작고 가벼워졌다고 말씀드리고 있지만 실제로 성능을 위해 고려한 여러 부분 때문에 일반적으로 자주 접하시던 발룬에 비해는 조금 무겁습니다.
