A string of #31 or #43 beads is next to useless at HF. Study
k9yc.com/RFI-Ham.pdf and see the "Cookbook" for recommendations of
chokes that DO work.
The purpose of a choke is to kill common mode current on the cable(s) on
which they are applied. That would, for example, prevent feedlines from
acting as radials, which could unbalance currents on the radials. It
would also prevent noise pickup on those feedlines.
