TrueRC Singularity 5.8 U.FL Lite Antenna

The TrueRC Singularity 5.8 U.FL Lite is a compact circularly polarised antenna for 5.8GHz video transmitters with a U.FL socket, made in Canada. It pairs an 11.8 mm head with a lightweight cable, suiting whoops, toothpicks and HD micro builds where every gram counts. TrueRC lists the Singularity U.FL for the DJI O3 and O4 air units, the Walksnail Avatar HD VTX and the Caddx Vista / RunCam Link, and it plugs into any analog VTX with a U.FL connector.

Key features

• 1.9 dBic gain across 5.6 to 6.0GHz
• 99% radiation efficiency with SWR of 1.5:1 or better
• 11.8 mm wide, 8.2 mm tall head that fits tight whoop canopies and printed antenna mounts
• Lightweight 1.37 mm U.FL Lite coax that routes easily through small frames
• Choice of 45mm or 72mm nominal length to match the run from VTX to mounting point

This is the RHCP version, so pair it with RHCP antennas on your goggles or video receiver; mixing polarisations costs a large share of signal. U.FL sockets are delicate, so fix the cable to the frame near the VTX to keep crash loads off the connector.
