Abstract

Field strength measurements were conducted at VHF and UHF for different base station antenna heights in the south Indian coastal zones in urban, sub-urban, quasi-open and open regions. These experimentally observed values are compared with different prediction methods like Hata, ITU-R, Blonquist & Ladell, Egli, and Tbrahim & Parsons. The results showed that in sub-urban and urban regions Hata´s method gave reasonable agreement with the observed values and in the open region gave better agreement at 440 MHz than at 150 MHz. All the other methods deviated appreciably from the observed values
