Webshort circuit and power cross event. III Lightning protection utilizing a Gas Discharge Tube, GDT, with SIDACtor. When lightning occurs the SIDACtor will react first causing voltage to increase across PPTC until GDT fires. Resistance of PPTC must be selected carefully for proper coordination. Applicable Standards: • IEC 61000-4-2 (ESD) WebIntroduction. Proper lightning protection is an important aspect of designing a safe amateur radio station. Recently, many amateurs have become concerned about possible damage from EMP, or Electromagnetic Pulse. Fortunately, EMP protection has been studied by Dennis Bodson, W4PWF, and effective mitigation strategies published in QST.
