Abstract
VHF television signals along the Cape West Coast are often degraded by fading and/or ghosts. The problem is analyzed from recorded signal strength data and a theory is developed that ducting, caused by a sloping temperature inversion, is the propagation phenomena causing the undesired effects. A meteorological explanation for the effect is given.
