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.
