Technical indicators: 1. Frequency bandwidth: 2.4GHz-2.483GHz 2. Polarization mode: linear polarization antenna 3. Impedance: 50Ω 4. Gain: 13dBi 5. Radiation angle: E=48° H=75° 6. Maximum wave ratio: (2.4GHz-2.83GHz) Less than 1.5 7. Maximum power handling: 30W 8. Connector type: B internal thread inner hole Colour: As Shown Material:plastic Important Tips: This antenna has a narrow radiation angle due to its high gain, so it is suitable for long-distance communication. For short-distance communication, the transmitting antenna and the receiving antenna must be aligned. If they deviate from the radiation range, the communication effect cannot be achieved. It is suitable for long-distance image transmission remote control of flying drones. Note: Installation guide not included, we strongly recommend you professional installation.
