Building my own balun, part 4: Deciding on where to put dipole ends and finishing it 4 days ago
I finally decided where to put the holes in the case for the dipole ends of the balun. This took some serious pondering! I made those holes, put screws through them and wound the ferrite core with enamelled copper wire. To guess the needed length of wire I first wound it with packing rope, made a small knot at the point where it was enough and unwound the rope to measure the length I used and took a bit longer wire. Using sanding paper I removed the enamel isolation from the ends of the wires and used soldering tin on it. Other parts of this project:
- Building my own balun, part 1: idea and parts needed
- Building my own balun, part 2: measuring the 'old' balun
- Building my own balun, part 3: First work on the case
- Building my own balun, part 5: First tests of the result
