How to choose a drone antenna

Concept: Unmanned aircraft, or UAV for short, is an unmanned aircraft that is operated either completely or intermittently autonomously by a radio-controlled device and self-contained program control device.

Function: The drone antenna is responsible for the signal transmission and reception between the drone and the remote control or the ground station, which plays a crucial role in ensuring the safe and efficient flight of the drone.

Application: With the gradual maturity of drone research and development technology, manufacturing costs are greatly reduced, and drones are gradually popularized in the market, which has immeasurable benefits in improving life production efficiency, reducing workload and production costs, improving accuracy and operational safety. At present, it has been widely used in agricultural plant protection, power inspection, express transportation, police law enforcement, geological exploration, environmental monitoring, forest fire prevention and film and television aerial photography and other fields.

How to choose a drone antenna:

When choosing an antenna for a drone, it is important to consider the specific application and your needs as an operator

1. Frequency: Determine the operating frequency range of the drone. Most drones use the 2.4GHz or 5.8GHz bands. Make sure you choose an antenna that is compatible with the drone's frequency.

2. Antenna type: There are many types of antennas, including omnidirectional antennas and directional antennas. The omnidirectional antenna sends and receives signals in all directions, making it suitable for general flight and FPV (first person View) applications. Directional antennas focus the signal in a specific direction, providing longer coverage and better signal penetration. They are ideal for long flights or areas with obstacles.

3. Gain: Antenna gain refers to its ability to focus the signal in a specific direction. Antennas with higher gain provide longer coverage and better penetration, but their beamwidth is narrower. Antennas with a lower gain have a wider beamwidth but a shorter coverage area. Consider your flying style and the coverage required to determine the appropriate gain for the antenna.

4. Polarization: The antenna can be linearly polarized (vertical or horizontal) or circular. In order to obtain the best signal strength, it is important to match the polarization of the drone's transmitter and receiver antennas. Circularly polarized antennas are more resistant to signal loss caused by drone orientation, making them a popular choice for FPV applications.

5. Connector Type: Make sure the antenna you choose has the correct connector type to connect to the drone's transmitter or receiver. Common connector types include N-type, SMA/RP-SMA, IPEX, and so on.
