All the courses and pubs in the folder are military related but there are plenty of antenna/radio theory and FEA (field expedient antennas) info that can still be applicable to the civilian world.
The course "Basic Radio Troubleshooting Guide" was created by me for an easy, afternoon course on the basics for an infantry platoon.
Enjoy!
