I'll take pix of the pole at the end of the street to identify a lightning arrestor. Dark now and there is a LED light that blinds the camera...

   

I looked online for a pix but many of the images are mis-identified and are on transmission lines, not the 7200 circuits.

Strangely, though I am subscribed to several radio forums, that, often make use of ferrite in many forms, I have never experimented with a ferrite loaded antenna. My preference is for vintage wire loops, I have several loops and radios built with them.

Though for most RF noise issues the portable radio works but it seems that in very strong sources a well shielded radio and a means to disable the AVC and having a calibrated "S" meter is employed...
Good luck tomorrow...
