The Lumenier Duality HD Stubby 2.4/5.8GHz Dual-Band Antenna for DJI Digital HD FPV Goggles V2. A circular polarized antenna specifically designed for the DJI FPV Drone Goggles. Duality antennas provide improved 2.4/5.8Ghz reception in a compact form factor. That's right, this antenna will work on both 2.4GHz or 5.8GHz frequencies!
The Lumenier Duality Antenna was created in partnership with world-renown antenna designer TrueRC to bring you the first Dual-Band aftermarket antenna designed as a direct replacement and upgrade for your stock DJI antennas found on the DJI Digital HD FPV Goggles V2. The Duality antenna was made from the ground up to be a perfect match for the DJI goggles. Duality antennas are form fitting, low profile, color matching, direct connect RP-SMA, and all this with improved performance.
The Lumenier Duality HD Stubby, like the extremely popular AXII 2 antenna, is both Circular Polarized (LHCP or RHCP) as well as Omni-directional. On top of that, it is also 2 antennas in one being able to effectively function as both a 2.4GHz and a 5.8GHz antenna. The Lumenier Duality has been further customized to be a direct fit for the DJI HD FPV Goggles. The Duality HD Stubby comes with a custom RP-SMA connector designed to directly and securely screw onto the DJI Goggles. No adapters needed! This makes for an ultra-compact and efficient setup since you don’t need to lose any dB with extra adapters.
The DJI FPV Drone has a linear polarization (neither LHCP nor RHCP). This means that either LHCP or RHCP will be an equal upgrade to the stock antennas on the goggles. If you also use the DJI FPV V2 Goggles with the DJI FPV Air Unit (DJI Digital FPV System), you need LHCP antennas assuming you did not swap to RHCP antennas on the Air Unit or Caddx Vista. If you purchase RHCP and use it with the stock DJI Air Unit antennas (LHCP) there will be greatly reduced signal performance. Never cross - polarize RHCP and LHCP.
If using DJI V2 Goggles with only Air Units / Caddx Vista, this is a better antenna combo: https://www.getfpv.com/lumenier-axii-hd-5-8ghz-antenna-combo-set-for-dji-digital-hd-fpv-goggles.html
Features
Performance Like No Other
The Duality antenna offers full 360 degree coverage with near perfect circularity and up to 2.8dBic gain. Unlike the stock linear antennas the Duality Circular Polarized antennas provide consistent results no matter the orientation of the aircraft or the goggles. Additionally, these antennas have an incredible cross-polarization rejection of up to -30dB.
All this performance means you can fly farther, and more confidently with a solid RF link.
Precision Tuning
Every Duality antenna comes from the factory having been precisely tuned by hand during assembly and QC. The unique "Fin" design on top is not there for only form but also function. These "tuning" fins allow each antenna to be individually and perfectly tuned during production. Good isn't good enough, Lumenier and TrueRC have stepped it up to the next level of precision manufacturing.
Dual-Band Antenna Technology
Designing a single band antenna of such incredible performance is hard enough, but doing this in a dual-band network is near impossible. Until now.
The Duality antenna features one of the most advanced CP Dual-Band networks available today. Not only does it have unrivaled performance but it managed to do this in an ultra-compact, 5g package. Where other antennas make sacrifices to reduce size the Duality antenna's patented design is able to keep all of the benefits while at the same time be incredibly small.
Quality Engineering with High Grade Materials
The Lumenier Duality antennas are produced with high quality, low loss materials. The material is key to a good quality antenna, and even more so when it comes to performance. This technology along with precision manufacturing results in a top of the line receiving antenna. It is designed to work with the DJI HD FPV Goggles for 2.4 and 5.8GHz, and it is capable of receiving signal up to many miles away.
The injection molded polycarbonate case of the Stubby protects the antenna elements allowing for easy, worry-free storage.
