Yagi Antenna: Key Advantages and Primary Applications
May , 16 2025
Key Advantages of Yagi Antennas: High Gain and Directivity Yagi antennas are highly directional, focusing radio frequency (RF) energy into a narrow beamwidth. This directional radiation pattern allows for significant gain (typically 8–15 dBi), making them ideal for long-distance communication. The focused beam minimizes interference from unwanted directions, improving signal-to-noise ratios. Cost-...
