Tall towers, that the UHF DTV transmitting antennas are mounted at the top of, tend to sway in the wind. This sway can be as much as a good fraction of a wavelength of the carrier frequency up on UHF. That, combined with some significant ghosts, can make the conditions at a receiver be constantly changing. Which adds extra fun in receiver decoder design...
