    The loss of operating distance due to the positioning of wireless antennas too close to the ground. Reflected RF energy from the ground gets mixed in with the direct RF signal and causes cancellation of RF energy at the antenna. In certain situations the loss can be significant. UHF systems are less susceptible to this effect than are systems that use VHF, due to the shorter wavelength of the former.
