웹Choke or current baluns force equal and opposite currents to flow. The result is that currents radiated back onto the transmission line by the antenna are effectively reduced, or "choked off," even if the antenna is not perfectly balanced..

This type of common mode choke is also effective as a 1:1 balun or unun. It prevents your feed line becoming an active part of your antenna. It is therefore also called a line isolator. A 1:1 balun is used to transform a balanced or symmetrical antenna to an unbalanced or unsymmetrical feed line. dwarf fortress how to butcher animal

"웹1일 전 · The basic principle is that two 1:1 baluns are used. The inputs are connected in parallel and the balanced outputs are connected in series, which provides a 4:1 impedance transformation. The bifilar pair used for the transmission line needs to have a characteristic impedance of 100 Ohms. " - Balun diy
