Which signal degradation increases in long-range RF transmissions when atmospheric ducts form?

💡 Explanation

Multipath interference increases because atmospheric ducts act as waveguides, reflecting radio waves. The reinforcement and cancellation of signals (Multipath Interference) is stronger. Therefore signal quality decreases, rather than decreased path loss if the antenna and receiver were in direct line-of-sight.
