I had a cheap scanner that used semi's on the input. The first
lightning bolt many miles away zapped them. Got out the soldering
iron and replaced. Same thing again, later. Pi$$ poor design.

Don't waste your time. Use an inductor that has nearly zero ohms DC
resistance, or your front end will suffer the same fate.

And the inductor is used how? In series it will block the RF. In parallel,
it will still look like a high impedance for the fast rise time spike of
a zap.
