Outdoor wireless services quality is greatly tarnished by the existence of coverage blind spots or any areas of inadequate reception. It is thus of interest to eliminate or fill in the blind spots in order to boost the receiving signal strength which ultimately leads to better service quality. The authors propose the use of a simple flat metallic reflector as a device to divert some energy in the service coverage towards the blind spots or any existing areas of inadequate reception. The method of moment is employed in analysing the effectiveness of the authors' proposed technique. Experiments have been carried out to verify calculation results as well as to find out on the proposed technique's viability. It is found that the elimination of blind spots by using a reflector is a viable approach. The received power at the blind spot locations are increased by about 3dB to 5dB when the reflector is present.
