웹2015년 4월 30일 · In television, amateur radio, and other antenna installations and connections, baluns convert between 300 ohm ribbon cable or 450 ohm ladder line (balanced) and 75 Ω coaxial cable (unbalanced) or to directly connect a balanced antenna to (unbalanced) coax. To avoid EMC problems it is a good idea to connect a centre fed dipole antenna to … 웹A balun is a form of transformer that goes from an unbalanced signal to a balanced signal. The unbalanced, or "single-ended" signal can be microstrip or stripline; the key characteristic is that one of the two conductors is clearly grounded. In a balanced signal, both conductors are equally "hot" with voltage; in reality there is always a true ...

For example, baluns can be used to send line level audio or E-carrier level 1 signals over coaxial cable (which is unbalanced) through 300 feet (91 m) of balanced category 5 cable by using a pair of baluns at each end of the CAT5 run. As the signal travels through the balanced line, noise is induced and added to the signal. As the CAT5 line is carefully impedance balanced, the noise induces equal (common-mode) voltag… 웹être ut ilisée (balun nécessa ire). antennas.biz. antennas.biz.
