WiFi Antennas
DIY WiFi antennas for extending wireless networks.
Many ham radio operators experiment with WiFi antennas, often adapting designs from amateur radio bands to the 2.4 GHz and 5 GHz spectrum. Building and testing these antennas offers practical experience in RF theory, antenna construction, and propagation characteristics, which directly benefits other ham radio antenna projects. Operators can extend the range of their wireless networks, create point-to-point links, or improve signal strength for various applications.
This category provides numerous homebrew antenna projects for WiFi, ranging from simple omni-directional designs to highly directional arrays. Hams can find detailed instructions for building popular types like the Cantenna, BiQuad, and helical antennas. There are also guides for constructing Yagi antennas and parabolic dish feeds, allowing operators to optimize their stations for specific coverage patterns and gain requirements. These projects are excellent for honing antenna building skills and understanding how different designs perform on the air.
