With the growing rise of 5G connectivity, LoRa networks, and GPS-based technologies, selecting the appropriate antenna gain is more important than ever. The efficiency with which an antenna directs radio waves is determined by its gain, which influences both coverage and signal intensity. A high-gain antenna enables long-distance transmission while focusing signals in a tighter direction, making it excellent for rural or outdoor applications. Meanwhile, a low-gain antenna provides more coverage and better performance in metropolitan locations with frequent signal reflections. For example, 5G networks benefit from directed high-gain antennas for higher data throughput, LoRa IoT systems rely on moderate gain for dependable long-range connectivity, and GPS antennas require consistent low-gain reception for precise location
