So we are not going to go in depth about why you need a communications plan, but rather offer concrete suggestions on communications in general and particular products that every prepper should own.

I am a licensed ham radio operator and have been participating in Skywarn spotter activities and off grid battery operated events for over ten years.  I am also a pilot and a licensed EMT, both activities in which radio communications are a matter of life and death.  I am not affiliated with any of the companies I recommend in this article nor do I stand to make any financial gain through any of them.
