L-band SATCOM and HF radio technologies each have unique space weather vulnerabilities that can impact required communication performance.  Sole reliance on either technology leaves a long range communication system vulnerable to unnecessary periods of outage or reduced performance.  Equipage with both technologies is the most effective solution for long range communications in support of airborne operations where reliable communication capability is expected when not in range of terrestrial; i.e. VHF communications….Read more
