WebThe best balun for this antenna is an air-core choke balun. Avoid using other types of baluns, such as ferrite sleeve or transformer type baluns. This antenna has a high reactive component at the feedpoint SWR of more than 2:1. The high SWR increases loss in ferrites and may cause excessive core heating, core saturation, or arcing in the windings. WebBaluns are designed to be transformers (like 1:1 4:1, 6:1, etc.) or choke baluns, and both. For an antenna, the purpose of a choke balun is to create a high-impedance to common mode currents that would flow on the outside of coaxial cable shielding.
