Dipole feeding balun on pcb
WebJan 24, 2024 · The corrective action is often a current balun that "forces" the same current into each part of the antenna in an effort to reduce the inevitable common mode current on the feedline. What is often overlooked in an end fed antenna design is that the current that is present on the half wave element needs a method of returning to the transmitter ...
