- Polarization: RHCP/LHCP
- SWR: ≤1.5 (ON 5.8GHz)
2. Setup and Installation
Proper installation of your iFlight Albatross antenna is crucial for optimal performance. Ensure that the antenna's connector type matches the port on your FPV goggles or drone's video transmitter (VTX).
2.1 Identifying Connector Types
The Albatross antenna is available with RHCP SMA, RHCP RP-SMA, or LHCP RP-SMA interfaces. Verify the connector type of your antenna and device before attempting to connect.

2.2 Connecting the Antenna
- Carefully align the antenna's connector with the corresponding port on your FPV goggles (e.g., Fatshark EV200D) or drone's VTX.
- Gently screw the antenna onto the port. Do not overtighten, as this can damage the connector. Hand-tightening is usually sufficient.
- Ensure the connection is secure to prevent signal loss during operation.

2.3 Polarization Matching
For best signal quality, ensure that the polarization of your transmitting antenna (on the drone) matches the polarization of your receiving antenna (on the goggles). Both should be either Right-Hand Circularly Polarized (RHCP) or Left-Hand Circularly Polarized (LHCP).
3. Operating Guidelines
The iFlight Albatross antenna is designed for 5.8GHz FPV systems. Adhere to the following guidelines for optimal performance:
- Frequency Range: Operate within the 5000-6000MHz frequency range for which the antenna is optimized.
- Line of Sight: Maintain a clear line of sight between your drone's transmitting antenna and your FPV goggles' receiving antenna for the strongest signal.
- Antenna Orientation: While circular polarization reduces multipath interference, orienting your antennas generally towards each other can improve signal strength, especially at longer distances.
- Avoid Obstructions: Physical obstructions like trees, buildings, or dense foliage can significantly degrade signal quality.
4. Maintenance and Care
To ensure the longevity and consistent performance of your iFlight Albatross antennas, follow these maintenance tips:
- Clean Connectors: Periodically inspect and clean the gold-plated connectors to remove any dirt, dust, or corrosion. Use a soft, dry cloth or a cotton swab with isopropyl alcohol if necessary.
- Avoid Bending: While the antenna cable is flexible (RG141), avoid sharp bends or excessive force that could damage the internal wiring or the connector joint.
- Storage: Store antennas in a clean, dry environment away from extreme temperatures and direct sunlight when not in use.
- Physical Inspection: Regularly check the antenna for any signs of physical damage, such as frayed cables, bent connectors, or cracks in the housing.

5. Troubleshooting
If you experience issues with your iFlight Albatross antenna, consider the following troubleshooting steps:
- Poor Signal/Video Breakup:
- Ensure both transmitting and receiving antennas have matching polarization (RHCP to RHCP, LHCP to LHCP).
- Check all connections for tightness and cleanliness. A loose or dirty connection can significantly degrade signal.
- Verify that your FPV system is operating on the correct frequency channel.
- Reduce distance to the drone or move to an area with fewer obstructions.
- Inspect antennas for physical damage. Even minor damage can affect performance.
- Antenna Not Fitting:
- Confirm that you have the correct connector type (SMA vs. RP-SMA) for your device. SMA and RP-SMA connectors are similar but not interchangeable.
