The work concentrates on the determination of the relationship between the signal strength of the WE FM, radio station, Abuja with respect to temperature and relative humidity. The WE FM radio station based in Abuja, Nigeria operates at the frequency of 106.3 MHz. The research was carried out, during cloudy and uncloudy days, with the use of CATV signal level meter, Hygrometer and thermometer to measure the signal strength, the temperature and relative humidity respectively. The results show that signal strength reduces as the atmospheric temperature increases, but the signal strength increases with the increase in relative humidity. The calculated correlation coefficients of the temperature and signal strength for the two days are -0.42369and -0.51878 while relative humidity and signal strength correlation coefficients are 0.29 and 0.39. These results further affirm that signal strength directly varies with relatively humidity and inversely varies with the ambient temperature. It was also found that the effect of these parameters on the signal strength of the FM station radio is higher during cloudy or rainy day than on clear or sunny day.
