What is a possible effect of a resonant ground connection?
Overheating of ground straps
Corrosion of the ground rod
High RF voltages on the enclosures of station equipment✓Правильный ответ
A ground loop
Объяснение
A ground conductor close to an odd multiple of a quarter wavelength acts as a stub that transforms the low impedance at the earth end into a high impedance at the equipment end. Current flowing into that high impedance develops high RF voltage on the equipment enclosures.
