Product Overview
AT1400 Flat Panel Directional Antenna is a high-gain, dual-band, dual-polarized directional panel antenna. Featuring long transmission range, stability, and reliability, it is suitable for outdoor installation with a tripod to enhance the control and data/video transmission range of drones.
Visual Specification Notes
The following product details were transcribed from the technical graphics supplied with this model.
- The AT1400 provides gain at 1.4GHz and enhances the data, image and control signals of smart devices, delivering strong long-distance anti-interference performance, more stable signals and lower transmission latency.
- Measured at 1.42GHz, the AT1400 main lobe reaches 13.8dBi with a 3dB angular width of 34.5 degrees, a main lobe direction of 90.0 degrees and a side lobe level of -17.3dB.
- The AT1400 is dual-polarized, supporting both vertical and horizontal polarization across the 1428MHz-1458MHz band, with a horizontal beam width of 34.5° and a vertical beam width of 38.6°.
- The AT1400 carries IP65 ingress protection and mounts on a 1/4"-20 UNC threaded hole with a depth of 42mm, so it can be tripod-mounted for outdoor use.
