SWR Plots of FPV Antennas – Know Your Best Frequency/Channel

Fpv Drone Antenna Vtx Vrx Video Transmitter Receiver 5.8ghz Testing Comparison Swr Measurement Litevna

Optimizing every aspect of your FPV drone setup is key to achieving the best video quality and range. Understanding the SWR of your 5.8GHz antenna can help decide which frequency or channel you should use for optimal performance. Not everyone has the tools to measure SWR, so I have conducted extensive tests on the antennas I own to share their SWR plots with you.

SWR Plots Explained

What’s antenna SWR: https://oscarliang.com/best-fpv-antenna/#SWR. Curious about measuring antenna SWR? Check out my tutorial for a deep dive into the process:: https://oscarliang.com/litevna-measure-antenna-swr/.

The antennas in this post are listed alphabetically. The plot markers are as follows: Marker 2 is at 5.6GHz, Marker 3 is at 5.8GHz (the center of the graph), and Marker 4 is at 6.0GHz. Marker 1 highlights where the lowest SWR is found within the sweep range of 5.4GHz to 6.2GHz.

Tips for Enhancing Your FPV Video Link

  • Selecting the Right Antenna: Consider antennas with consistently low SWR across the channels you frequently use.
  • Channel Optimization: Use the SWR charts to identify which channels offer the best performance for your selected antenna.
  • Matching Receiver Antennas: Ensure that antennas for the receiver have a matching resonance frequency for the best results.

Conclusion

SWR plays a pivotal role in achieving reliable FPV video links. By understanding antenna SWR, pilots can make educated decisions, selecting the most suitable antennas and frequency/channel for their flights. I plan to continue testing more antennas and will regularly update this post. If you have any particular antenna you want me to test, let me know in the comment. Happy flying!

When I got the LiteVNA and tested my collection for SWR it helped me root out some bad antennas that were making my video performance seem random. So that’s all sorted out and I took the opportunity to mark on my antennas with an L (low), M (medium), H (high) to better pick when flying with friends which channels they might perform better with. It was also suprising to me how much SWR varies between identical antennas.

Heyy Oscar! Thank you so much for this gem of a blog. Can you please test the TBS triumph antenna and the pagoda-2 antenna? (The red top that says designed by Maarten Baert)
Thank you!!❤️

Hello! It would be great to see GepRC Momoda antenna

Thank you, it’s a great article.
It would be interesting to test the HDZero Freestyle VTX antenna.
However, perhaps we can consider that this antenna is the ‘Runcam Link Air Unit Antenna’ because it closely resembles it

I haven’t touched my HDZero gear for almost a year and I totally forgot I have those antnneas LOL
I will get them tested in the next batch!

Hey, great article, I’d suggest adding a pagoda and a triple feed patch antennas to the test, they’re very widely used. Cheers

Sure, I will try to include them in my next batch!
