Web19 de mar. de 2024 · 1 Answer. The sleeve balun acts as an RF choke, preventing RF current from flowing on the outside surface of the coaxial cable shield. It helps to think of the sleeve and the outer surface of the coaxial cable shield as the outer and inner conductors of a coaxial line. Because it's shorted at the lower end and is one-quarter wavelength long, …
