SWR testing 1:1 common mode choke balun design from TRX Bench
Testing SWR on a 1:1 balun common mode choke found on TRX Bench channel. Please see the link below to review his excellent work.
I cannot test common mode attenuation since I do not have the right equipement at this time. The only thing I can test for the moment is the SWR across all HF amateur bands using a dummy load and my radio. I think that it will prove that impedance seems to stay stable across the bands even though the wire specification is unknown.
I have a follow up video on testing the attenuation performance of this balun choke using a nanovna here : https://youtu.be/k2DAyvciyow
Please visit TRX Bench videos about the BalUn subject.
