1400-1600MHz 2dBi RHCP drone antenna

Product Introduction

1.The 1400-1600MHz dedicated frequency band is designed to meet the high-frequency communication needs of drones. This band is the preferred frequency for remote control and image transmission for mid-to-high-end drones (such as those used for industrial inspection and professional aerial photography). Compared to lower frequency bands, it offers higher signal transmission rates (supporting 4K HD image transmission) and is less susceptible to interference from consumer wireless devices (such as Wi-Fi and Bluetooth).

2.RHCP circular polarization technology ensures stable signal reception in complex environments. The RHCP design perfectly matches the polarization of drone image transmission and remote control signals. Compared to traditional linearly polarized antennas, it effectively reduces signal reflection, obstruction, and loss, improving signal reception efficiency by over 30%. Even in strong electromagnetic interference or highly dynamic flight scenarios, it maintains a stable connection, resolving the pain point of linearly polarized antennas, which often experience disconnection due to angle deviation.

3.Low VSWR + high impedance matching ensures lossless and efficient signal transmission: VSWR <1.5, far exceeding the industry standard of ≤2.0, significantly reduces signal reflection loss, ensuring over 90% transmission efficiency of 1.6GHz high-frequency signals from the antenna to the drone terminal. The standard 50Ω impedance precisely matches the drone's communication module, further reducing energy waste. Combined with 2dBi gain, it ensures stable coverage of 1.5-3 km while avoiding the narrow beam problem caused by high gain. This balance of coverage and signal strength makes it suitable for medium- and long-range drone operations.

4.Vibration-resistant and weather-resistant, environmentally compliant, reliable in harsh environments: Passing rigorous vibration testing at 10-55Hz, 1.5mm amplitude, and 2 hours, it withstands high-speed drone flight (≤80km/h), takeoff and landing shock, and air turbulence, preventing performance failure caused by loose internal components. Operating temperature range: -40°C to +85°C, with a humidity range of 5% to 95%, it operates stably in high-altitude, freezing mountainous areas, and humid coastal and rainy environments.

5.Compact size and easy installation adapt to drone space constraints: Measuring only ⊘40.5×168mm, it is lightweight and only one-third the size of a typical mineral water bottle. It can be easily installed on the drone's fuselage, wings, or gimbal without affecting the drone's aerodynamic layout or flight maneuverability.
