The 120 vac inverters draw a LOT of current from the 12 vdc side. The clamp-on ferrites, especially 31 mix, are likely saturated by the DC current alone. This renders them ineffective for RF energy.

Being terribly facetious: Let's all fire up our spark transmitters connected to the best HF antenna we have. Would FCC then, act? Absolutely! How is solar much different? Don't need an old Ford spark

Yes, I do. I have a clamp-on bead on the coax at both the HamStick end and the 7300 end. I also use a 120-foot long wire as a counterpoine that I usually pitch up into a pine tree. Since it carries c
