Drone, UAV and UAS ADS-B Out Antenna, Blade Type, Description
ADS-B Out Antenna, Model UL-1030-733, intended for use on Drone, UAV and UAS airborne platforms. This Blade Antenna supports transponders operating in modes 1090ES and 978UAT.
Its thin and lightweight (80 g) design makes this ADS-B Blade ideally suited for remotely piloted airborne platforms, where weight load is at a premium. Operation covers the entire range of 950-1150 MHz, which includes the light craft (under 18,000 ft) frequency of 978 MHz, the interrogator frequency of 1030 MHz, and the large aircraft (above 18,000 ft) ADS-B frequency of 1090 MHz.
This ADS-B Out antenna has an internally shunted design, where all conducting components are electrically tied to the SMA connector's body for simple Electrostatic Discharge (ESD) management. Thus, measurement across the SMA connector at low frequencies (with an ohmmeter) should report a short circuit. However, at the operating frequencies of 950-1150 MHz, the input impedance at the connector is 50 ohm nominally.
Similar Drone/UAS models to be available for Wi-Fi/LoRa, S-Band, C-Band, X-Band, Ku-Band in 2025.
