[Elecraft] Balun Questions

[Ron D'Eau Claire]

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.
