Abstract

This paper Presents the measurement of electromagnetic field strength of Treasure FM transmitter operating at a frequency of 98.5MHz in Port Harcourt and its environs with the aid of an Automated Band Scanner GPS system. The measurement were carried out by taking the radio Station’s transmitter as a reference point at the Centre and selecting 24 measuring points around the transmitter. These points were selected with 1km spacing taken as the interval between two measuring points, summing up to a total of 6km due North, East, West and South of the Radio Transmitter respectively. The result obtained was critically analyzed and interpreted with the aid of an attenuation decay curve. The behavior of the signal was seen to be a function of the Ground Constant of the terrain, reflection of the signal from the earth surface, Diffraction by obstacles and transmitter parameters such as transmitter Power, Antenna Gain and Antenna Height.

Keywords: Attenuation, Automated Band Scanner, Radio Transmitter, Received Signal Strength
