    Designing and Optimizing Repeater Using Telecom Microwave Antenna case of Fana Broadcasting Corporate (FBC) and Ethiotelecom
    (Addis Ababa University, 2024-03) Efnan Merga; Murad Ridwan (PhD)
    Microwave antennas are widely utilized in telecommunications, radar systems, satellite communications, and television broadcasting to transmit programs—such as relaying an outside broadcast to a main studio—as well as in other applications requiring the transmission of high-frequency electromagnetic waves over long distances. Fana Broadcasting Corporation (FBC) currently utilizes microwave links to transmit public and governmental programs from temporary outside broadcast (OB) studios across Addis Ababa to its main headquarters studio. However, the city’s complex terrain and the rapid rise of tall buildings frequently obstruct the line of sight between transmitters and receivers, leading to an increased occurrence of failures during live television broadcasts. This thesis addresses the identified challenges by designing and optimizing an EthioTelecom microwave antenna to function as a repeater for broadcasting. It evaluates the impact of substituting ITU-R parameters with Localized values, such as rain fading, to enhance performance.
