What is a possible effect of a resonant ground connection?
- A.Overheating of ground straps
- B.Corrosion of the ground rod
- C.High RF voltages on the enclosures of station equipment (correct answer)
- D.A ground loop
WhyA resonant ground connection can produce high RF voltages on the enclosures of station equipment. When a ground connection happens to be resonant at the operating frequency, it presents high impedance instead of a low-impedance path to ground, letting high RF voltages build up on the chassis and enclosures of connected station equipment, answer C. That's a distinct effect from strap overheating, rod corrosion, or a ground loop, none of which follow directly from resonance.
