Telecommunication industry enabled personal and professional communications and has been a significant tool used in most businesses. Even in times od pandemic, telecommunication was instrumental in the prompt dissemination of updates, government programs, data analysis which enables the government to successfully combat the COVID 19. A microwave link is a type of communication system using a beam of radio waves to transmit information between two fixed locations. Antenna is one of the basic components of a microwave link, together with the receiver, transmitter and transmission lines. One of the common topics in microwave communications is finding the antenna heights, since the heights of the antenna defines radio horizon. There are two methods on computing antenna heights. The single obstruction method, and the double obstruction method. A feature of Microsoft office such as MS WORD, MS EXCEL, MS Power point, the trendline can be used to determine the antenna heights. Trendline is normally used to depict trends and resistances to trends. This research shows that adding some manipulations make trendline a better way to solve antenna heights, that is free of trials. It can solve any type of terrain or obstruction types present between two communicating sites. With trendline, the result is the most practical height, and the answer is always final, no trial and error required. A close-ended survey is also undertaken to determine the level of acceptability of using the process. In most of the statements, the respondent agreed on the viability of using trendline to solve for antenna heights.
