DJI Part 04 MMCX Straight Antenna for FPV Air Unit User Manual

สินค้าเกินview

The DJI Part 04 MMCX Straight Antenna is designed for use with DJI FPV Air Units, providing reliable signal transmission for your FPV system. This pair of LHCP (Left-Hand Circularly Polarized) antennas features an MMCX connector for secure attachment and is engineered for long-distance transmission with strong anti-interference capabilities.

คำแนะนำการตั้งค่า

1. ระบุตัวเชื่อมต่อ: Locate the MMCX antenna ports on your DJI FPV Air Unit. Ensure they are clean and free of debris.
2. Align and Connect: Carefully align the MMCX connector of the antenna with the port on the FPV Air Unit. Gently push the connector straight in until you feel a distinct click, indicating a secure connection. Avoid twisting or forcing the connector.
3. Repeat for Second Antenna: If using both antennas, repeat the process for the second antenna on the corresponding port.
4. การวางตำแหน่ง: Once connected, position the antennas to ensure optimal signal reception. Avoid placing them directly against carbon fiber or other materials that may obstruct the signal. For best results, ensure they are oriented away from each other and have a clear line of sight.
5. ตรวจสอบการเชื่อมต่อ: Gently tug on the antenna cable near the connector to confirm it is firmly attached. A loose connection can lead to signal loss.

บันทึก: These antennas are LHCP (Left-Hand Circularly Polarized). For optimal performance, ensure that your receiving antennas (e.g., on FPV goggles) are also LHCP.

แนวทางปฏิบัติ

• การตรวจสอบก่อนบิน: Before each flight, visually inspect the antennas for any signs of damage, bends, or loose connections.
• การวางแนวที่เหมาะสมที่สุด: Maintain a clear line of sight between your FPV Air Unit antennas and your receiving antennas on the goggles. Obstacles such as trees, buildings, or even your own body can degrade signal quality.
• หลีกเลี่ยงการรบกวน: Operate your FPV system away from strong sources of electromagnetic interference, such as Wi-Fi routers, high-voltage power lines, or other radio transmitters.
• การรับรู้ช่วง: Be aware of the operational range of your FPV system. Signal quality can diminish significantly at the edge of the range, potentially leading to video feed loss.
• ปัจจัยด้านสิ่งแวดล้อม: Adverse weather conditions (e.g., heavy rain, fog) can affect signal propagation.

การซ่อมบำรุง

• การทำความสะอาด: If the antennas become dirty, gently wipe them with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
• การตรวจสอบ: Regularly inspect the antenna cables and connectors for any signs of wear, fraying, or damage. Pay close attention to the MMCX connector for any bending or corrosion.
• พื้นที่จัดเก็บ: Store the antennas in a clean, dry place, away from direct sunlight and extreme temperatures. Avoid bending the cables sharply or placing heavy objects on them.
• การจัดการ: Always handle the antennas by the base or cable, avoiding excessive force on the radiating element (the top cylindrical part).

การแก้ไขปัญหา

• Poor Video Signal:
  • Ensure antennas are securely connected to the FPV Air Unit.
  • Verify that both transmitting (Air Unit) and receiving (goggles) antennas are of the same polarization (LHCP in this case).
  • Check for obstructions between the drone and the pilot.
  • Inspect antennas for physical damage.
  • Test in a different location to rule out environmental interference.
• Antenna Disconnection:
  • Ensure the MMCX connector clicked into place during installation.
  • Avoid excessive strain on the antenna cables during flight or handling.
  • If connectors appear worn or damaged, replacement may be necessary.
