TrueRC Singularity 5.8GHz RHCP MMCX90 Short 45mm
by True RC

The TrueRC Singularity 5.8GHz RHCP MMCX90 Short (45mm) is an ultra-compact, ultra-lightweight circularly polarized FPV antenna engineered for race quads, micro drones, and tight CineWhoop builds where minimizing weight and drag is critical. Combining TrueRC's miniaturized element housing with high RF performance, the Singularity 5.8 delivers 1.9 dBic gain, 99% radiation efficiency, and excellent cross-polar rejection across the 5.6GHz to 6.0GHz frequency range.

Featuring a right-angle 90-degree MMCX connector and a short 45mm flexible stem, this low-profile antenna sits close to the frame to prevent snagging during racing and high-speed maneuvers. Built to absorb impacts while eliminating video noise and multipath interference, the RHCP Singularity 45mm antenna provides a clear, reliable analog or digital video link in compact FPV setups.

Key Features

• Ultra-Compact Radiating Head: Tiny 11.8 mm x 8.2 mm element housing minimizes weight and aerodynamic drag without sacrificing circular polarization coverage.

• 99% Radiation Efficiency: High RF efficiency maximizes video signal range, penetration, and clarity.

• 45mm Short Profile: Ultra-short cable stem keeps the antenna close to the drone frame, reducing crash exposure and snag points.

• Right-Angle 90° MMCX Connector: Plugs directly into MMCX-equipped video transmitters (VTXs) without placing strain on the PCB connection.

• High Cross-Polar Rejection: -15 to -30 dB rejection suppresses multipath reflections, signal bounce, and ghosting.

• Impact-Resistant Construction: Semi-rigid cable and rugged outer casing absorb crash impacts while keeping the radiating element protected.
