Transmission bounce is best described as radio transmissions that have bounced off a large object. Which term matches this description?

• A. Transmission bounce
• B. Tropospheric ducting
• C. Doppler shift
• D. Ground wave propagation

Answer: (A)

When radio waves encounter a large object, they can reflect off its surface and reach the receiver via a secondary path. This bouncing or reflection of energy is the phenomenon described by “transmission bounce.” It emphasizes the idea that the signal has been redirected by a large surface rather than traveling directly.

Tropospheric ducting involves signals trapped and guided by atmospheric conditions, not reflection from a solid object. Doppler shift is a change in frequency due to relative motion between the source and receiver, not a reflection. Ground wave propagation refers to energy traveling along the Earth's surface, not bouncing off a specific object.
