Which transmission loss increases when radio signals encounter atmospheric ducts?

A)Multipath Interference
B)Free-Space Path Loss
C)Absorption by rain
D)Antenna impedance mismatch

💡 Explanation

Multipath interference increases because atmospheric ducting causes abnormal radio propagation via refraction and reflection, creating multiple signal paths. Therefore, signals arrive at different times, leading to constructive and destructive interference, rather than simple path loss in a homogenous medium.
