FrSky Tandem TDMX Dual Band Receiver 2.4GHz & 900MHz

The Tandem series of dual-band receivers, unlike other FrSky receivers that operate solely at either 2.4Ghz or 900Mhz frequencies, can operate simultaneously on both frequencies. As a result, Tandem receivers offer low latency, long-range control, and high reliability, with improved anti-interference performance. The receivers employ a triple antenna design that provides wide and multi-directional signal coverage. Despite being newly designed, the 900Mhz antenna offers high performance similar to that of previous 900Mhz antennas. The TD MX model, a small and light board, provides 4 PWM channels and several onboard ports such as SBUS Out, S.Port, and FBUS, which enables seamless pairing with multiple telemetry devices and simplifies the build setup. Additionally, the Tandem receivers possess a built-in black-box function, which records data related to power and signal during flight under unusual circumstances. The main features of the Tandem receivers include simultaneous dual-band TD m
