Numerical analysis of the SIGAnatel tool for technical feasibility studies of TV and FM broadcast channels

This paper describes the applications of the SIGAnatel tool to simulate technical feasibility studies of TV and FM broadcast stations. The numerical analysis was performed using point-to-area field strength data and prediction methods based on Recommendation ITU-R P.1546-1. The SIGAnatel data bank on terrain roughness data was included in the simulations. Comparative studies between this work and SIGAnatel results were realized to verify the main parameters involved in the feasibility computations. The simulations include two proposed broadcast stations localized in Campina Grande city, Brazil: TV channel 13 and FM channel 288.
