>>Air core coils are of questionable value as common mode chokes, for
reasons I articulated in k9yc.com/RFI-Ham.pdf
>>The better solution is a ferrite core choke with balls. :)

Air core is better than cracked ferrites and melted coax in those little pvc

worry about getting enough ferrite mass to handle whatever burned up those
supposed 3kw rated 'baluns'.
