Transmission bounce refers to:

• A. Radio transmissions received that have bounced off a large object
• B. Radio transmissions that travel via satellite
• C. Radio transmissions that are encrypted
• D. Radio transmissions lost in rain

Answer: (A)

Radio waves can be reflected by large objects, producing a bounce that lets a signal reach a receiver via a path other than the direct line-of-sight. This reflection, or skywave/multipath behavior, explains how signals can be received after bouncing off surfaces like the ionosphere, mountains, or tall buildings. It’s the reflection causing the signal to arrive at a different location than the transmitter, not relaying through a satellite, not encryption, and not rain-induced loss. So the description of transmissions received after bouncing off a large object best matches this concept.
