STUDY AND EVALUATION OF RADIO FREQUENCY GROUNDING SYSTEMS.
Abstract
An R.F. earth ground, per se, should not be required in an electronic system if the system has been properly designed, installed and maintained - except where an earth ground system is a functioning part of an electronic system. The only justification and need for conducting R.F. energy to an earth ground would be when all the electromagnetic energy, within an electric or electronic system, has not been completely utilized and other means for control, including such conventional techniques as filtering, relocation of equipment, tuning circuitry and shielding, have been found uneconomical or impractical. If the R.F. energy is then to be conducted to earth ground, modification of a conventional National Electrical Code (NEC) ground becomes necessary. As the stateof-the-art does not offer reliable methods for the control of electromagnetic energy by means of conduction to earth, such modifications therefore cannot always meet the exacting requirements for complete elimination or attenuation of this energy. Solutions are suggested to cope with unutilized R.F. energy. (Author)
