DUO 3 Signal Booster is a portable tri-band signal booster designed for professional use in UAV operations and wireless communications. It operates simultaneously on 2.4G, 5.2G, and 5.8G bands, supports IEEE 802.11a/b/g/n/ac standards, DSSS and OFDM modulation, and TDD technology for rapid transmit/receive switching.
DUO 3 automatically manages frequency and channel selection, minimizes interference, enhances link stability, significantly extends control range, supports OcuSync and Lightbridge, and complies with FCC and CE requirements.
⚠️ Before use, ensure compliance with local regulations regarding radio-frequency equipment.
🫡 We are a team of veterans
We select and test equipment in real operational conditions. DUO 3 has demonstrated stable performance across three bands, low transmission latency, reliability in harsh environments, and sufficient autonomy for extended missions. In active EW environments, results will always depend on terrain, interference conditions, and the drone’s own hardware limitations.
