General exam question G3C03
Subelement G3, RADIO WAVE PROPAGATION· Group G3C
Why is skip propagation via the F2 region longer than that via the other ionospheric regions?
- A.Because it is the densest
- B.Because of the Doppler effect
- C.Because it is the highest (correct answer)
- D.Because of temperature inversions
WhySkip propagation via the F2 region is longer than via the other ionospheric regions because the F2 region is the highest. Because the F2 region sits highest of all the ionospheric layers, a single hop off it covers more ground than a hop off the lower E or F1 regions, which is why F2 skip reaches farther, answer C. Density, the Doppler effect, and temperature inversions aren't what drives the longer hop distance here, altitude is.
