Practical readiness guides. Skills first — what works when systems fail.
### – Build Antennas
Wire lengths, dipole / inverted-V basics, and SWR tuning so your radio can actually get out.
### – Radio Examples
VHF/UHF for local family and neighbors; HF when you need distance without the cell network.
### – Satellite System Comparisons
Iridium, Inmarsat, Globalstar, Thuraya — coverage and limits when internet and cell are gone.
### – Solar & Off-Grid Power
Loads, batteries, panels, controllers, inverters, vehicle charge, and generator backup — so radios, lights, and critical gear stay alive when the grid is not.
