The Lumenier AXII DUO 5.8GHz Patch Antenna offers you the highest performance you can get from a high gain mini patch antenna designed for FPV. The Lumenier AXII DUO Patch has an industry leading 12.2 dBiC gain for long range flying and excellent penetration through objects compared to standard omni-directional FPV antennas. It also features a best in class 95% 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 DUO 5.8GHz Patch Antenna.The AXII DUO builds on the same principles as the high performing AXII Patch Antenna, but the DUO doubles the receiver elements resulting in increased gain and performance. Each DUO contains 2x active elements installed with extreme precision ensuring optimal performance across the entire 5.8GHz band. With an incredible 280MHz wide bandwidth you'll get great signal no matter which channel you're on.High Gain and Wide Beam WidthGenerally with such a high gain antenna you would have to sacrifice the effective FOV (field of view) or beam width, but with the AXII DUO you get the best of both worlds: High gain and wide beam width! Compared to a similarly rated Helical antenna at 12.5dBiC you will only get 30 degrees of FOV, however the AXII duo with give you an incredible 12.2dBiC gain while still covering over 80 degrees of horizontal beam and 40 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.Compact Size with a Protective Injection Molded CaseNot only does the AXII DUO have awesome performance, but it does this in an ultra-compact form factor (73x35x9mm) and weighing only 18g. This makes the antenna an ideal choice as a long range goggle mounted receiving antenna. Since it is so small and compact you don't have to worry about bumping into things while wearing this antenna like other larger and heavier high gain antennas.The injection molded polycarbonate case fully protects the antenna elements inside allowing for easy, worry-free storage. The case is sealed with a ultra-sonic weld and is shock-resistant to protect from accidental drops.Precision Engineering with High Grade MaterialsThe Lumenier AXII DUO Patch Antenna features 2 sets of ultra-thin active elements suspended above the reflector, which allows for a higher velocity factor and lowers losses. This technology along with precision manufacturing results in a top of the line receiving antenna. It works great on both video goggles or ground stations for 5.8GHz, and capable of receiving signal up to many miles away. Check out our VTX antennas and our selection of Lumenier products!
