How can electronic devices be protected from radio interference?

[WOLFBOX]

What electronic devices do you bring when you off-roading/camping/hunting?
Do you have any practical ways of protecting electronic devices from being intervened by high frequency radio? It would be much appreciated. Thanks.

Time for some traps and caps and balun attacks.... it's actually a complex subject and it's best approached as a "what are you trying to keep from getting into what?" rather than a general spray and pray.
