The purpose of this research is to investigate how to exploit frequency and polarization techniques in reducing the effects of jamming against UAV relay communication links in an urban warfare environment. There have been early studies investigating the diversity techniques against multipath and fading problems in urban environments. A medium without any jamming issues seems almost impossible to exist in todays warfare. Basically, noise jamming issues were taken into consideration. Urbana Wireless Toolset was used as the computer simulation. Even though it is a powerful tool to predict the radio wave propagation in urban environments, due to the problems about modeling the cities lack of detail, like the shapes of the buildings, objects and vehicles that could be found in the streets, and other details that would contribute to the propagation mechanisms, it can only give us a trend with some guidelines instead of an exact mapping of propagation.
