Intercepting high frequency radio signals

High frequency radio signals are relatively easy to intercept, requiring only a suitable area of land in, ideally, a "quiet" radio environment.

High Energy Radio Frequency guns allow adversaries to create denial-of-service scenarios against a wide variety of targets. The concept behind the HERF Gun is very simple and they are incredibly easy to build. Depending upon the size of the power source used and range or accuracy desired, HERF guns can be designed to take many different shapes and forms. HERF Guns direct a blast of high energy radio signals at a pre-selected target.
