News and Communications
                                 

In a non EMP event cell phones will work. The network will be overloaded with voice calls. Text messages will work better. They have generators at the cell towers.

If you have a ham radio operator in your compound prepper group.  Support him with building Faraday building around his equipment, putting up antennas and building a repeater station. 

CB radios are a good way to communicate between compounds and farms

If you have Sirius satellite radio built into your car I would invest in a stand alone car radio kit to put in your Faraday cage.  This will provide news and FEMA information on evacuations, rescues, shelters and supplies.

Ask several members of the compound to share the monthly expense of a satellite telephone.
