웹A Balun is used to "balance" unbalanced systems - i.e. those where power flows from an unbalanced line to a balanced line (hence, balun derives from balance to unbalanced).As an example, consider a coaxial cable connected to a half-wave dipole antenna shown in Figure 1. Figure 1. An unbalanced transmission line (coaxial cable) connected to a dipole antenna. 웹2024년 5월 20일 · This balun will help you match the impedance of your HF transceiver to the slightly higher impedance of the delta loop antenna.
