What does a dummy load do?

• A. Converts transmitted energy into heat
• B. Prevents RF energy from being transmitted
• C. Amplifies the transmitted energy
• D. Filters out noise

Answer: (A)

A dummy load provides a non-radiating RF load that safely absorbs the transmitter’s power and turns it into heat inside a resistor. This lets you run the transmitter, tune equipment, or test gear without sending a signal out as radio waves. It’s usually designed to match the feed line impedance (often 50 ohms) and to handle the transmitter’s maximum power, so energy is dissipated as heat rather than radiated. It doesn’t block transmission—the energy is still produced, but the load absorbs it instead of creating an antenna signal. It doesn’t amplify energy either, since it’s a passive device. And it doesn’t filter noise; there’s no filtering function involved.
