Dual-Band High-Gain Directional Grid Parabolic Antenna
This product is an ultra-high-gain, dual-band directional grid parabolic antenna engineered specifically for long-range Unmanned Aerial Vehicle (UAV) ground base stations, tracking systems, and point-to-point data backbone links. Operating seamlessly across the 1900–2600 MHz and 4900–5900 MHz bands, it offers unparalleled peak gains of 21 dBi and 24 dBi respectively. The open-frame welded steel/aluminum grid structure provides exceptionally low wind loading while ensuring superior structural stability, making it an ideal choice for high-throughput video and telemetry streaming over extreme operational radii in remote field deployments.
Engineering Justification for Polarization & Beamwidth: For a grid parabolic antenna yielding ultra-high gains of 21/24 dBi, Dual Slant Polarization (±45°) is dynamically configured. At extreme distances ($>15 ext{ km}$), signals suffer severe atmospheric refraction and cross-polarization degradation. ±45° Dual Slant polarization establishes a highly isolated dual- channel MIMO network to maximize throughput while offering robust polarization diversity gain to neutralize signal fading caused by UAV airframe banking or crosswind drift. The high gain inherently results in an extremely narrow,laser-like beam (Horizontal beamwidth compressed down to 9° in the 5G band), necessitating active auto-tracking deployment.
