ANALISIS MODEL PROPAGASI OKUMURAHATA UNTUK LINK TERRESTIAL ANTENAPEMANCAR TV TOWER TURYAPADA

This research analyzes the performance of the Okumura-Hata propagation model in designing terrestrial link antennas for digital television transmitters at Tower Turyapada,Pegayaman Village, Buleleng. The findings are important for optimizing signal quality in regionswith geographical challenges, such as mountains and valleys, which obstruct signal propagation.The primary focus of the study is to measure and compare signal field strength at four test pointsin North Bali using simulations to predict the performance of the propagation model under differenttopographical conditions. The simulation results are then compared with theoretical calculationsto assess the model's accuracy and evaluate their alignment with established reference values.The results show that the Okumura-Hata model is not suitable and does not fully reflect thecomplex topography of Buleleng, as the simulation results were lower than the reference values.The study recommends using an alternative propagation model more suited to local geographicalconditions, along with more detailed field measurements to ensure optimal signal qualitythroughout the coverage area.
