Analysis of Electromagnetic Radiation of Radio Waves Propagation in Okene, Kogi State, Nigeria
Keywords:
Radio waves, Attenuation, Impedance mismatch, Path loss, EM fields, EM Spectrum, Propagation patternAbstract
The poor radio signals experienced in Okene and its environs have posed serious concern. This poor EM wave causes increased attenuation, which have resulted in distorted signals. This study considers two radio broadcast stations. The signal strengths of the two radio stations were compared and analysed. The signal strengths were measured using field strength meter. Sixteen locations were considered, while the wavelength and free space path-loss calculated. The approximate distances between the antennas were determined. The transmitting signal strength was 100.9dBµV (KA) and 102.2dBµV (KB). Receiving signal distances are 72.0km (KA) and 69.0km (KB). The free space path loss was 109.01dB (KA) and 109.39dB (KB). Though, transmitting signal strength of KA is lower with longer wavelength 3.21m and lower frequency 93.5MHz gives it an edge over KB which has higher frequency 109.5MHz and shorter wavelength 2.94m. It is however recommended that the FM stations should improve their network system for effective service delivery, mostly where low performances are experienced. Expectation is that at about 69km from transmitting antennas, booster stations will enhance signal effectively. This will lead to better signal quality and improved the satisfaction of the residents.
