duct propagation
1duct propagation — A layer of troposphere bounded above and below by layers that have different refractive index, which confines and propagates an abnormally high proportion of VHF (very high frequency) and UHF (ultrahigh frequency) radiation. This results in freak …

4radio duct — The layer within which the state of superrefraction exists. The meteorological requirements for superrefraction conditions are the presence of a temperature inversion and the rapid decrease of height. Ducting seldom occurs below 1000 MHz. For the …
