TBS Unify Pro HV 5G8 – Race (SMA)

TBS Unify Pro HV 5G8 Race (SMA) – Precision FPV Racing Transmitter

The TBS Unify Pro HV 5G8 Race is engineered specifically for competitive FPV pilots who demand stable signal performance, rapid configuration control, and race-safe transmission behavior. Designed for high-speed drone environments, this compact 5.8GHz video transmitter delivers consistent analog video with minimal interference and professional-grade RF reliability.

Weighing approximately 7 grams (without antenna), the unit integrates seamlessly into lightweight racing frames. Its 2–6S voltage compatibility eliminates the need for additional regulators in most builds, simplifying installation while maintaining electrical stability across varied battery setups.

TBS Unify Pro HV Output Power & Race Performance

This transmitter supports selectable 25mW and 200mW output levels, allowing pilots to adapt to race regulations or extended practice sessions. The robust RF amplifier design enables safe power-up procedures and maintains clean video output even during rapid throttle transitions. Unlike conventional transmitters that create interference spikes during startup, this model integrates CleanSwitch technology to ensure interference-free channel transitions.

TBS Unify Pro HV PitMode Racing Technology

PitMode reduces output power to an ultra-low level, allowing pilots to power on their quad without disturbing others on the grid. This feature is essential in organized racing events where multiple pilots operate simultaneously. The ability to test video feed and system performance before launch improves operational confidence and safety.

TBS Unify Pro HV SmartAudio V2 Control

SmartAudio V2 enables remote configuration of band, channel, and power directly through the flight controller or OSD. This eliminates traditional dip-switch adjustments and simplifies race-day setup. The split Audio and Data pins allow cleaner wiring and improved signal management within modern flight stacks.

For optimal signal coverage, pairing this transmitter with a directional antenna such as the TBS 5G8 RHCP Patch Antenna can significantly improve reception stability during long straightaways or structured race tracks.

For advanced ground reception systems, pilots may also consider high-gain options like the GEPRC 5.8GHz Patch Antenna to enhance directional signal acquisition.

Interference Control & Clean Transmission

CleanSwitch technology prevents signal sweep interference during power-up and frequency changes. This ensures neighboring pilots remain unaffected while adjusting channels. Such controlled RF behavior is particularly valuable in race events with multiple simultaneous video feeds.
