← ScienceWhich phenomenon leads antenna near a conducting surface interfering constructively receiving radio waves?
A)Ground wave propagation enhancement
B)Fresnel zone clearance improvement
C)Image antenna constructive interference✓
D)Tropospheric ducting signal amplification
💡 Explanation
When an antenna is near a conducting surface, it creates an 'image antenna' due to reflection causing constructive interference if phases align, amplifying the signal. Therefore image antenna interference results, rather than enhanced ground wave, Fresnel zone clearance or tropospheric ducting, which use different propagation mechanisms.
