Ghost JR Module
Product details
Slot the Ghost JR Module into any JR-bay radio — Taranis, RadioMaster, and others — and upgrade to a 2.4 GHz link built for both racing and long-range FPV. Four RF profiles cover everything from 222 Hz pure-race speeds to low-rate long-range. End-to-end latency sits around 4 ms with OpenTX. Designed in Switzerland by ImmersionRC.
Features
- 2.4 GHz worldwide ISM band — 76 MHz of bandwidth, clean in crowded race environments
- Four switchable RF profiles: Pure Race (222 Hz), Race (166 Hz), Normal (62 Hz), Long Range (15 Hz)
- ~4 ms end-to-end latency with OpenTX
- 16 µW – 350 mW uplink power (region-dependent)
- Twin 2.1 dBi dipole antennas with Tx-side diversity
- Chirp Spread Spectrum with Adaptive FHSS — robust against interference
- Bidirectional binding with protocol negotiation
- USB firmware upgrades; OTA updates for paired receivers
- Integrated OLED + joystick for on-module configuration (no Lua scripts needed)
- Supports SBus and GHST (auto-sense)

FAQs
Please read our FAQs page to find out more.
What is the main function of the T28 tracking system?
The T28 automatically tracks and maintains communication with unmanned vehicles by continuously pointing its antenna toward the moving platform based on position, altitude, and orientation data.
What types of antennas can be used with the T28?
The system supports patch, Yagi, and parabolic grid antennas, as well as omnidirectional options. It can operate with either a single or dual antenna setup depending on mission requirements.
Is the T28 compatible with other datalink systems?
Yes. The T28 can integrate Embention’s SDL datalinks as well as third-party systems such as Silvus, DTC, and Microhard through its protected expansion bay.
Can the T28 be controlled manually?
Yes. While it offers automatic tracking through integrated sensors and telemetry data, it can also be operated manually using external control interfaces.
Is the T28 suitable for outdoor or mobile use?
Absolutely. With its anodized aluminum construction, IP54 protection, and wheeled transport case, the T28 is built for field deployment and outdoor operation in all conditions.
