Product overview
The Jumper 370M+915M Dual-Band Transmitter Module provides a radio link for FPV racing, long-range flight, and professional missions. Its ELRS GEMINI configuration operates at 370MHz and 915MHz, with transmission power specified as 1000mW at each frequency. The module combines a rugged housing with active forced-air cooling and heat dissipation that adjusts with power output for high-temperature environments. TCXO stability supports control across varying temperatures. Electrical integration requires a DC 6-8.4V supply, while dual-band fusion supports 370 and 915MHz antennas.
Physical integration uses a JR-slot mount and an SMA antenna interface. The module supports JR/NANO bays with plug-and-play compatibility for most transmitters, alongside compatibility with most open-source ERLS receivers and remote controls. USB-C provides an upgrade interface, and Wi-Fi and Bluetooth support upgrades and maintenance. The 370MHz band offers minimal interference for use in mountainous areas, dense forests, underground environments, and private networks. The 915MHz band serves long-range penetration applications. Compatibility remains qualified to most equipment within the stated categories.
