I hate to showcase my ignorance but what is a  1µH  and where do I get one?

As I said, they originally had a 3 el vertical array on MW but one of the masts had collapsed when one of the parafil guys melted due to the high intensity field and collapsed during a storm .

2.2mH is a large value. I guess its purpose be protection against statics. 1uH has is a low impedance at MW providing some highpass but maybe not enough in presence of a nearby station. Try it in any case.

Great. Simpler idea. Elektor sdr design by Burkhard Kainka  had 2.2mH inductor across antenna
