Hi guys, Power cable extension for AH-4... this is 4-conductor 18 AWG, unshielded. I'm trying to completely block CM current from my vertical and plan to run 2 of these chokes on the cable (see attached)-- one just below the tuner and another before the cable enters the shack. Present iteration is about 12 turns thru 3 stacked Mix 31's (x2 as indicated). Will this choke the current and/or do you have other suggestions? I have plenty of additional toroids (3rd choke in the middle of the cable?) and also some 4" ones. Thanks!
