The Lumenier AXII is known to be the most versatile and highest performing antenna line for FPV today. Lumenier has been able to improve on the best and make it even better! Improved Features Significantly Improved Range with a Higher Gain (2.2dBic Gain) Wider Bandwidth (5.3-6.2GHz) Cleaner Signal And Better Rejection to Interference More Durable - Improved Injection Molded Housing Virtually Perfect Axial Ratio While almost every aspect of the AXII 2 was improved upon, the size and weight managed to stay the same. The AXII 2 is still one of the smallest and lightest circular polarized antennas on the market, perfect for lightweight racing builds, freestyle quads, and your FPV goggles! The AXII 2 comes in many connector types such as SMA, MMCX, U.FL, Stubby SMA, and Long SMA. Precision engineering has given this antenna a virtually perfect 1.0 Axial ratio resulting in a true circularity. On top of that, the AXII 2 has an amazing max gain of 2.2dBic, a true upgrade over the original AXII. Super Tough Antennas take a lot of abuse, especially when put onto a quad. The AXII 2's robust antenna housing is made out of a new injected molded polycarbonate, and ultra-sonically welded shut. This has significantly improved the durability of the AXII housing. The 160mm long semi-rigid RG402 cable allows for 90 degrees or more of freedom. The SMA connection is reinforced with a metal collar crimped to the base for extra support. Note: When installing, secure the antenna via the SMA connector, do not twist the cap. Specifications Gain: 2.2dbic Axial ratio: 1.0 (near perfect) Bandwidth: 5.3GHz-6.2GHz Radiation Efficiency: 98% SWR: <=1.5:1 Weight: 12.7g Size: 105mm x 17.5mm Cable: Semi-rigid RG402 Connector: Right-Angle SMA Works great as both a transmitting or receiving antenna Compatible with other styles of 5.8GHz RHCP antennas Polarization Left Hand Circular (LHCP) Includes 1 x Lumenier AXII 2 Right-Angle SMA 5.8GHz Antenna (LHCP) Videos Design by and manufactured by Patent Pending.
