A commonly asked question is what material should be used for an RF choke. For the HF bands, the best material to use is Type 77 (or 73) ferrite beads. About 6 Amidon FB-77-1024 beads side over RG-213 and can be held in place with heat shrink. (Do not attempt to glue the beads together.) This balun should be located just below the base of the Hex-Beam, never within the elements or above it. Type 43 material is not appropriate for HF, but is the material of choice for VHF and UHF.
