This research work examines the effects of variation in temperature on signal reception of Direct broadcasting satellite (DBS) on Ku-Band in some selected towns in Nasarawa State, Nigeria. Data used were obtained through experimental approach of recording both relative humidity and the quality of signal received from DBS at 12.517GHz at regular interval of one hour covering two climatic conditions (Rainy and Dry seasons) in 2018. The data obtained from field was used and daily and monthly averages were evaluated. The result showed a consistence in the values of temperature across the three towns (Akwanga, Keffi and Lafia) under study largely to the fact they lie within same coordinates. All the towns experience gradual rise in temperature value as the hours of the day progresses and declined again as night falls, largely due the absence of solar energy radiation at night. While, this was observed, the quality of signal reception reduces from its highest value in January to its lowest value in month of August. The result showed that, the state has temperature values of 38oC and 23oC as high and low values respectively. The averaged value for the whole states showed a weak negative correlation coefficient value of -0.298 and coefficient of determination (R2) value of 0.077 when fitted into linear regression between temperature and the quality of signal reception within the study areaKeyword: Temperature, direct broadcasting satellite, signals reception quality, Akwanga, Keffi and Lafia
