3. Setup

Proper installation of your FPV antenna is crucial for optimal performance. Follow these steps to set up your Foxeer Lollipop 4 Plus antennas:

1. Identify Connector Type: Ensure your video transmitter (VTX) or FPV receiver (VRX/Goggles) has an RP-SMA connector. The Foxeer Lollipop 4 Plus antennas provided are RP-SMA.
2. Secure Connection: Carefully screw the antenna onto the corresponding connector on your VTX or VRX. Hand-tighten only; over-tightening can damage the connector. Ensure the connection is firm to prevent signal loss during flight.
3. Antenna Placement: Position the antenna away from carbon fiber frames or other conductive materials that can block or interfere with the signal. For best results, ensure the antenna has a clear line of sight in all directions.
4. Polarization Matching: For optimal signal quality, ensure that both your transmitting antenna (on the drone) and receiving antenna (on your goggles/ground station) have matching polarization (both RHCP in this case).

Note: If your VTX/VRX uses an SMA connector, you will need an appropriate adapter (not included) to use these RP-SMA antennas. Using mismatched connectors or adapters can degrade performance.

4. Operating Instructions

Once the antennas are correctly installed, follow these general guidelines for operation:

• Pre-Flight Check: Before each flight, visually inspect the antennas for any damage, loose connections, or bends that might affect performance.
• Power On Sequence: Always power on your FPV goggles/receiver first, then your drone's video transmitter. This ensures the receiver is ready to capture the signal.
• Maintain Line of Sight: While circular polarization helps mitigate multipath interference, maintaining a clear line of sight between your drone and receiver will always yield the best video signal.
• Avoid Obstructions: Flying behind dense objects like trees, buildings, or hills can significantly degrade signal quality and range.
• Monitor Signal Quality: Pay attention to your video feed for signs of degradation (static, breakup). This indicates you may be approaching the limits of your signal range or encountering interference.

5. Maintenance

To ensure the longevity and consistent performance of your Foxeer Lollipop 4 Plus antennas, consider the following maintenance tips:

• Regular Inspection: Periodically check the antenna for any physical damage, such as cracks in the housing, frayed cables, or bent connectors.
• Cleaning: If the antenna becomes dirty, gently wipe it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the shell.
• Connector Care: Keep the RP-SMA connector clean and free of debris. If necessary, use a small brush or compressed air to clean the threads and center pin.
• Storage: Store antennas in a protective case or bag when not in use to prevent damage from impacts or crushing.
• Avoid Excessive Bending: While the IRoot Reinforcement Design allows for flexibility, repeated or extreme bending at the same point can eventually lead to cable fatigue.
