Its basic principles apply to all EM radiation, including RF/wireless and optical energy, and it is often used in optical applications. Here, we’re only looking at RF.

Yagi Antennas with Dual Polarization - PCTEL

WebbThe Yagi antenna’s components are often fused to a conducting tube or rod at their centers. Being such a directional antenna, Yagi antennas are usually favored for conditions limited to a single polarization. Because of their high power handling capability and large directivity, Yagi antennas can be utilized for long-distance transmission. WebbThe antenna can be used in two possible modes. In normal mode the antenna radiates horizontally polarized radio waves perpendicular to its axis. In axial mode the antenna radiates circularly polarized radiation along its axis. detroit lions green bay packers prediction
