They go by names such as “tropospheric ducting” and “sporadic E.” And sometimes they do spooky things with radio waves. Take the strange case of WPBX-FM in Southampton, N.Y., the Long ...

Radio engineers call it “ducting,” when atmospheric conditions in the summer wreak havoc with radio signals. And there’s not a whole lot that can be done about it, they say.

This was created by atmospheric ducting, the refraction or guiding of electromagnetic radiation to follow the curvature of the Earth. The result whether it is radio waves or light being bent is ...

The DX Info Centre Tropospheric Ducting Forecast site provides a six-day forecast of potential VHF, UHF and microwave radio and TV anomalous propagation. News and Business; ... The forecast predicts ...

“If a transmitting antenna extends into a duct of cool air, or if the radio wave enters the duct at a very low angle of incidence, VHF and UHF transmissions may be propagated far beyond normal ...
