In the last three decades, the great powers have become increasingly dependent on satellite communication (SATCOM), very high frequency (VHF), and ultrahigh frequency providing high bandwidth line-of-sight communications. These military communication channels lack resilience because an electronic warfare (EW) campaign can affect both VHF and SATCOM simultaneously. The 1940s preferred spectrum, high frequency, with its different propagation patterns, offers an opportunity for military communication resiliency in the 21st century. The concept of retrograding could give an operational advantage and create the ability to sustain communication in EW saturated environment. & DEFENSE FORCES, COAST guard, homeland security, and emergency management agencies have, during the last decades, become dependent and reliant on stable communications providing ample bandwidth to support operations and information flow within the organization. The current deployed tactical and operational communication networks are highly dependent upon lineof-sight (LOS) communication utilizing very high frequency (VHF), ultrahigh frequency (UHF), and higher frequencies. The information grids are
