Balun rf design
웹2024년 4월 11일 · And while theoretically there may be other possible designs for a 1:1 current balun, in practice "1:1 current balun" means "a common-mode choke with balanced and unbalanced connectors on it". The name choke refers to the electrical component, whereas the name 1:1 current balun refers to the job it is doing. 웹DX Engineering has the expertise to design and build a better balun that will deliver more power to the antenna, ...
