Determination of the Coverage Areas of VHF Television Signal in Ilorin, Kwara State, Nigeria

Abstract

This study investigates the coverage areas of Nigerian Television Authority (NTA), Ilorin in Kwara State by means of quantitative measurement of the television signal level. The signal levels of NTA Ilorin, Channel 9, were measured radially along several routes with the transmitting station at focus. Their corresponding distances from the transmitting station and locations were also measured. These measurements were taken using Digital Signal Level Meter, GE-5499 and GPS 72 – Navigator. Measurements were taken radially along several routes in Ilorin Local Government Area and environs until the signal faded away completely. From the data obtained, surfer 8 application software was used to draw the contour maps of the signal levels around the transmitting station to show the coverage areas around the state. The results obtained showed that the present configurations of the transmitter for the television station did not give an optimum coverage area. The television signal, covers only 7.66% of the entire land mass of Kwara State
