General exam question G4C11
Subelement G4, AMATEUR RADIO PRACTICES· Group G4C
What technique helps to minimize RF “hot spots” in an amateur station?
- A.Building all equipment in a metal enclosure
- B.Using surge suppressor power outlets
- C.Bonding all equipment enclosures together (correct answer)
- D.Placing low-pass filters on all feed lines
WhyBonding all equipment enclosures together helps minimize RF hot spots in an amateur station. Bonding every piece of station equipment's enclosure together equalizes the RF potential across the whole station, eliminating the localized points where RF energy would otherwise build up as "hot spots" on ungrounded metal, answer C. Enclosing gear in metal, using surge suppressors, or adding low-pass filters address different problems (shielding, transient protection, and harmonic suppression) and don't specifically solve RF hot spots caused by unequal grounding.
