Abstract

The study aims to compare the influence of some components of the atmosphere like wind speed, rainfall, temperature, atmospheric pressure and relative humidity on the strength of the signal received (SSR) via digital terrestrial television reception in Abuja, the Federal Capital Territory, and Jos, Plateau State. The parameters of the atmosphere were obtained using automatic weather logger, and a CATV signal strength meter, in two selected locations (Jos, Plateau State and Abuja, Federal Capital Territory) between 2019 and 2020. The results show that the SSR of both AIT and Unity TV fails to correlate with atmospheric pressure, temperature, rainfall as well as wind speed, but are strongly influenced by relative humidity for the period of study. The implication is that, when the rainfall, atmospheric temperature, wind speed and atmospheric pressure increase, the SSR of the two televisions stations decreases, and vice versa. On the other hand, the greater the relative humidity, the greater the SSR of the television stations; since the humidity or water moisture in the atmosphere would reduce the temperature of the atmosphere which should have caused signal attenuations. The percentage of relationship between the SSR of AIT with atmospheric temperature is 90.4%, pressure is 10.4%, relative humidity is 88.5%, wind speed is 96.0% and rainfall is 31.5% based on the coefficients of correlation, while percentage of relationship between the SSR of Unity TV by atmospheric temperature is 94.0%, pressure is 6.3%, relative humidity is 91.5%, wind speed is 50.4% and rainfall is 33.5% based on the coefficients of correlation. Although, the percentage of relationship of temperature in Jos is higher than in Abuja, the effect is less significant on SSR in Jos compared to AIT, Abuja, probably due to the low annual temperature of Jos as well as the higher altitude of Jos compared to Abuja. It could be as a result of the short distance (10 km) between the transmitter and receiver in Jos compared to the distance (18 km) between the transmitter and receiver in Abuja. The results will find usefulness to Nigeria Broadcasting Commission (NBC) being a regulatory body would ensure compliance with well-developed operational guidelines for improving quality of signal performances. It will also serve as benchmarks for digital link budgeting in other parts of Nigeria.
