An electromagnetic pulse (EMP) resistant telecommunications (telecom) system includes core components mounted within and shielded by a Faraday cage. The components include a data source or storage device. An ethernet switch selectively connects the data source or storage device to a primary satellite router and a post-EMP satellite router. Telecom signals are output from and input to the core components via low noise blocks (LNBs) and block upconverters (BUCs). A method of resisting EMP interference for a telecommunications system includes the steps of enclosing and shielding core components in a Faraday cage and providing output via LNBs and BUCs to an antenna subsystem. The antenna subsystem can include one or more antenna elements with configurations chosen from the group comprising: parabolic dish; array; unidirectional; and omnidirectional. The EMP-resistant telecom can optionally be combined with a signal regenerating subsystem and used with a signal regenerating method.
