The Rebirth of High Frequency

The resurgence of interest in High Frequency (HF) communications is driven by emerging vulnerabilities in satellite technology, which have become the primary mode of global communication since the 1970s. As military and government sectors recognize the risks posed by anti-satellite weapons, jamming, solar storms, and coverage gaps, they're reinvesting in HF, which leverages skywave propagation. This shift highlights a strategic pivot towards more resilient and reliable communication methods, crucial for national security and emergency response systems.
