General exam question G3C09
Subelement G3, RADIO WAVE PROPAGATION· Group G3C
What type of propagation allows signals to be heard in the transmitting station’s skip zone?
- A.Faraday rotation
- B.Scatter (correct answer)
- C.Chordal hop
- D.Short-path
WhyScatter propagation allows signals to be heard in the transmitting station's skip zone. Scatter propagation is what lets a station hear signals inside what would normally be a silent, unreachable skip zone, since scattered energy can reach places direct skywave refraction skips right over, answer B. Faraday rotation, chordal hop, and short-path propagation are all separate phenomena that don't describe signals showing up inside the skip zone.
