The Lumenier AXII HD 5.8GHz Antenna Set for DJI Digital HD FPV Goggles. A set of circular polarized, directional antennas specifically designed for the DJI FPV Goggles. Designed to provide long range 5.8Ghz video reception in a compact form factor. Finally, a high-quality set of antennas designed as a direct replacement and upgrade for your stock DJI antennas for the DJI Digital HD FPV Goggles. The AXII HD antennas were designed from the ground up to be a perfect match for the DJI goggles. The AXII HD antennas are form fitting, low profile, color matching, direct connect RP-SMA, and all this with improved performance. The Lumenier AXII HD 5.8GHz Patch Antenna offers you the highest performance you can get from a high gain mini patch antenna designed for DJI Digital HD FPV. The Lumenier AXII HD Patch has a high 8.2 dBiC gain for long range flying and excellent penetration through objects compared to standard omnidirectional FPV antennas. It also features an incredible 92% efficiency (most mini patch antennas are below 75%), which means you get amazing performance and the best picture in your video goggles. Lumenier, designed in collaboration with renowned FPV antenna designer Hugo of TrueRC, brings you the Lumenier AXII HD 5.8GHz Patch Antenna. Form Fitting Design for DJI HD FPV Goggles Not only do the AXII HD Antennas have awesome performance, but they do it in an ultra-compact form factor (only 7mm thick) and weighing only 22g including connector and cable. This makes the antenna an ideal choice for your DJI HD system. Each Patch antenna come with double-sided foam tape for a form-fitting direct mounting solution to your goggle’s faceplate. Since it is so small and compact you don't have to worry about bumping into things while wearing these antennas like other larger and heavier high gain antennas. Super easy to store in your travel bag as well, and no need to remove the antennas while traveling. The injection molded polycarbonate case of the Stubby fully protects the antenna elements inside allowing for easy, worry-free storage. The case is sealed with an ultra-sonic weld and is shock-resistant to protect from accidental drops. High Gain & Wide Beam Width Generally, with such a high gain antenna you would have to sacrifice the effective FOV (field of view) or beam width, but with the AXII HD Patch Antenna you get the best of both worlds: High gain and wide beam width! The AXII HD Patch will give you 8.2dBiC gain while still covering over 68 degrees of horizontal beam and 68 degrees vertically. This means the antenna is more forgiving and can still give you a clear picture even if you aren't pointed exactly at your aircraft or transmitter. Precision Engineering with High Grade Materials The Lumenier AXII HD 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 5.8GHz, and it is capable of receiving signal up to many miles away.
