Bottom line, I never leave anything connected antenna wise during a thunderstorm. Best way to protect your beloved sets. Yes a long wire would help SW reception, possibly dramatically. I do believe you already have a built in loop for the AM BCB band anyhow. 100' of wire. Good ground as close as possible to the set. Meaning an 8' copper rod driven down, leaving maybe 6" for connection to a ground cable (not a thin wire), back to the radio chassis (ground connection). Works wonders many times for unwanted man made noise control in these old sets. Plus can actual aid in reception for obvious reasons. I've noticed many collectors over look a good proper ground, or are simply unable to use one due to living in an apartment or whatever.
