    From my conversation with the guy at Palomar Engineers, five ferrite snapon beads placed up as close to the feedpoint as possible. For your RG-8U, Palomar Engineers FSB-1/2.

    If making a coax choke balun, about 21' (17 turns on a pc of 4" pvc pipe).

    I used LMR-200, which is a low loss coax the same size as RG-58.

    I have the ferrite beads on the coax for my portable antenna, and the coax coil type on my main antenna.
