Understanding how efficiently your RF system transfers power is essential for optimizing antenna performance, minimizing losses and protecting your transmitter. This free VSWR to Return Loss & Power Calculator instantly converts Voltage Standing Wave Ratio into key RF metrics, including return loss in dB and reflected power percentage. Whether you’re tuning an antenna, testing a…

An Ugly Balun, also known as a coax choke, is one of the simplest and most effective ways to suppress unwanted common-mode currents on an antenna feed line. By winding coaxial cable into a properly sized air-core coil, radio operators can reduce RF interference, stabilize antenna performance, and improve overall station efficiency. The Ugly Balun…
