I would like to add a balun/choke to my dipole for the reasons outlined in Using a balun with a resonant dipole.In the spirit of continued kit and/or DIY building for my ham shack, I set out to investigate how I might best proceed "from scratch".

The core's outer diameter is 34 mm and the inner diameter is 22 mm (not critical). The teflon wire (AWG18) was purchased from dx-wire.de. The sealed ABS box (item G302) is from Velleman.
