Building my own balun, part 7: Better measurements of the result 10 months ago
Homemade balun version 2 SWR scan 1-60 MHz 20180424
Homemade balun version 2 SWR scan 10 meter band 20180424Time to do measurements of the revised attic antenna. And now with a voltage balun with more windings the balun is working better, showing ok SWR values. A nice optimum in the middle of the 20 meter band (although I originally wanted that optimum near the digital mode part) and a nice optimum in the 10 meter band (also somewhat higher than originally planned). Comparing them to the original measurements show an increase in frequency in both SWR curves. So I consider this a good result! Time to get it on the air and make contacts again. Next step, working on an outside dipole with the Fritzel balun. Other parts of this project:
