Описание: Building a 1:1 current balun is one of the most effective ways to prevent "common-mode" current from flowing down the outside of your coax, to be exact, on the outer surface of the coaxial shield. This keeps RF out of your shack and ensures your antenna radiation pattern stays true to the design. Using RG316 on a proper ferrite core is an excellent choice for 400W, as it is high-temperature Teflon-insulated coax that can handle the heat. I have chosen 400W for the discussion as that is the legal limit for my class of license, though I do not have a 400W radio! Read More: https://johnsonfrancis.org/techworld/...
