Ham Radio General Class Practice Test

What is one good way to avoid unwanted effects of stray RF energy in an amateur station?

1. Connect all equipment grounds together

2. Install an RF filter in series with the ground wire

3. Use a ground loop for best conductivity

4. Install a few ferrite beads on the ground wire where it connects to your station

The correct answer is: Connect all equipment grounds together

Connecting all equipment grounds together is a good way to avoid unwanted effects of stray RF energy in an amateur station because it helps create a common reference point for all equipment, minimizing differences in ground potential that can lead to issues such as noise or interference. When all the equipment grounds are interconnected, it reduces the likelihood of ground loops, which can pick up or radiate RF energy, causing unwanted signals to be introduced into the system. This common grounding strategy enhances the overall stability of the signal paths in the station. It prevents potential differences that could result in unwanted currents flowing through the ground, which might degrade performance or create safety hazards. By having a unified ground point, the system is better shielded against interference, leading to clearer communication and a more efficient operation of the amateur station.
