R9 TDMX

Frequency: 2.4GHz & 900MHz Dimension: 25*21*4mm (L*W*H) Weight: 7.1g Operating Voltage: 3.5-10V (Please ensure the supplied voltage exceed 3.5V during the use.) Operating Current: ≤185mA@5V Compatibility: Tandem series transmitter & TD protocol capable RF module Triple 2.4G/900M Antenna– 2* External 2.4G antenna (IPEX1)– 1* Newly designed 900M antennaIt only matches with the Tandem series transmitters with dual-band transmitter module. The Tandem dual-band receivers are unlike any other FrSky 2.4Ghz or 900Mhz receivers, they work simultaneously at both 900Mhz and 2.4Ghz frequencies. That means Tandem receivers provide not only the low latency signal and long range control, also benefits from enhanced level of high reliability and anti-interference performance. The Tandem series receivers adopt the triple antenna design that provides multi-directional wide coverage for the remote signal. The 900Mhz antenna is a newly designed small form factor, but has the equivalent high-p
