This Jeti REX 7 is 7 channel full-range receiver compatible with JETI EX & EX Bus protocols. Supports telemetry functions. Dual dipole antennas where the length is an extra long 40cm. This makes it ideal for challenging RF installations in heavily shielded areas. Easily install away from pieces such as carbon fiber reinforcements, steel jet engine thrust tubes or any other conductive or structural pieces. An excellent solution for fully moulded F5J electric gliders, F3J gliders, carbon fibre 3D Aerobatic Airplanes, Drones, EDFs and Jet models. Additional features: PPM input PPM output Integrated expander for EX & EX Bus devices UDI digital output JETI Duplex receivers are designated for use with the DC/DS transmitters or the JETI transmitter modules in the 2.4 GHz frequency band. The receivers support online updates so that everyone is able to install the latest software versions. From the very beginning bidirectional transmission has been a distinctive feature of the Duplex system, this not only handles telemetry data, but it also helps to ensure secure primarily transmission safety between the transmitter and receiver. The Duplex EX telemetry system uses an open protocol. This gives the advantage of compatibility with a large number of telemetry sensors from both JETI model and third-party producers. For the display of telemetry data you can use purposely designed equipment like the JETIBOX profi and DC/DS transmitters or you can display the data on PCs. The REX receivers are fully compatible with the previous generation of the Duplex equipment.
