I wound two split-bead chokes for use with my Little Tarheel II antenna on my Ford F150. One choke is for the reed-switch and the other is for the screwdriver motor. 16 turns on a MIX31 fer-rite split-bead for each choke.

The wires are terminated with Anderson Power-poles. The wire is shrink-wrapped for a clean look. No common-mode current shall be seen by my LT II!
