Realistic radio modeling is crucial for accurate simulation of wireless networks. This paper examines the effect of using directional antennas in real environments with non-trivial multipath effects. We find that the actual variation in signal strength as a function of antenna direction differs appreciably - sometimes dramatically - from what the antenna power (gain) pattern alone would suggest. We quantify and analyze this difference across several antenna types and environments, and provide a generalizable parametric model to support more realistic planning, simulation and analysis.
