I would like to build a good high power common mode choke for 160m.
I have a piece of RG393/U ptfe 10mm coax. (1 meter)
I was thinking of using this and make me a "W2DU style" choke.
Searching for the ferrite cable cores, i found on the Mouser website 2
types which would fit:
Fair-rite 31 material : https://www.mouser.be/ProductDetail/623-2631626402
Laird LF material : https://www.mouser.be/ProductDetail/875-LFB187102-000
Laird got a higher impedance at 1.8 Mhz.
I think a lot of ham's on this topband reflector got more experience, so
what's your advice ?
Thanks, Gert ON4GPE
