Abstract: In this research paper we investigated the effect of different path loss parameters with respect to distance in northen region of India (State: Punjab and Jammu) by using low and high power RF transmitter. In order to achieve good and reliable reception a practical broadcast engineers must know the suitability of appropriate model so as to design the various parameters of a transmitting station for achieving the high quality of signal at a known distance. In this paper we have taken field strength measurements for 100w FM and 10KW FM station at almost identical distances (50 Km) in different locations. All the measurements (readings) have been taken with the help of anritsu site master and by using the suitable anritsu dipole antenna. Comparative study of all graphs has been taken with respect to FCC f(50,50) curves. In this paper, various investigations and their graphs have been plotted to show a comparative analysis of different parameters. In our measurements, we have used receiving antenna of 4 meter height and subsequent conversion has been applied to convert measurement (readings) into 9 meter receiving antenna height.

Keywords: Path loss, field strength, RF transmitted power, Receving antenna height, dipole antenna etc.
