JR® Dual Modulation Spectrum System (DMSS) 2.4GHz protocol offers a secure radio link that combines DSSS and FHSS capabilities into a wide-band transmission system that includes high-speed response and high resistance against RF noise. Another outstanding benefit is the JR bi-directional DMSS communication system and the real-time telemetry information it delivers. Receiver voltage telemetry is standard with every DMSS receiver, and add-on sensors will give you real time feedback of information from your model such as the RPM of an aircraft propeller or helicopter rotor blades, temperature and altimeter readings. Telemetry modules from JR for the DMSS systems have a dual purpose and are available for various applications. The RA03T unit is designed to work both with the JR DMSS Dual Diversity Antenna receivers such as the JR RG712BX Receiver, as well as an upgrade to the DMSS RA01TL equipped receivers listed below. The addition of the RA03TL increases your signal diversity when placed apart from the standard dual diversity coaxial antenna equipped on the main receiver unit. The RA03TL includes a coaxial antenna unlike the chip-type antenna thats best used when it can be located away from signal blocking materials such as a battery or engine.
