A favorite of mine for transmission line transformers or common-mode chokes (a.k.a. "baluns") is to use a twisted pair instead of coax. Cheap and effective and with a little calculation you can approximate any impedance line you want.
K2 builders know this technique from winding T6 in their rigs. 73, Ron AC7AC -----Original Message----- >>>> I would have concern that long term usage of RG-8X, being foam core >>>> dielectric material and bent in a tight radius, may allow the >>>> center conductor to migrate to the inside radius of the bend.
