DUO II 2.4/5.8G + Accessories for DJI drones The ALIENTECH DUO II signal amplifier is a fantastic, active directional antenna with two power amplifiers to extend the range, usable in the frequency band 2.4 GHz-2.4835 GHz and 5.725 GHz-5.850 GHz. With significant transmission gain of 28-30dBi and significant receiving gain of 23-25dB, it can increase wireless signal strength, extend transmission distance and stabilize signal reception, and supports wifi and OcuSync protocol. This ALIENTECH DUO II signal amplifier is compatible with DJI RC, MAVIC Mini 3 Pro and Mavic 3 Classic. The Quick Release function saves maximum time preparing for take-off. Inside the booster are two rechargeable 18650@2500 mAh lithium batteries, which can be used continuously for more than 300 minutes each time. This product is specially developed for the 2.4 GHz and 5.8 GHz frequency bands. 2.4G is IEEE 802.11B/G/N compliant and 5.8 is a bi-directional power amplifier that complies with IEEE 802.11A/N. The product conforms to frequency spreading techniques such as direct sequence (DSSS) and orthogonal frequency division multiplexing (OFDM). The use of TIME DIVISION DUPLEX (TDD) fast microwave detection technology and linear power amplifier technology greatly extends the wireless high-frequency communication distance while keeping the transmission speed of 802.11B/G/N wireless devices unchanged.
