Would not a bnc-to-banana plug adapter hooked to a doublet made from 100' of zip cord be equally useful? Is there even a reason to have a balun in-circuit? I've read the characteristic impedance of the zip cord (or speaker wire, etc.) is about 75 ohms. If you "unzipped" 67 feet or so and put on a tie wrap (to avoid further unzipping), you'd have a quite serviceable 40 meter dipole with an SWR of 1.5:1 or so.
