Order TrueRC Singularity 1.3 GHz for clear video over long distances
TrueRC is a Canadian manufacturer of premium FPV antennas. The company was founded in 2014 in Quebec. The brand specializes in antennas for long-distance flights and racing. The range includes models from the Singularity, Core, X-Air and Stubby series. TrueRC also produces antennas for 2.4 GHz, 5.8 GHz and 1.3 GHz.
- 99% radiation efficiency for maximum range.
- Cross-polar rejection -15 to -30 dB.
- Lightweight 18 grams for FPV builds.
- SWR (SWR) no more than 1.5:1 for a clean signal.
- Axial ratio 1.0 for perfect circular polarization.
How the TrueRC Singularity antenna works
The antenna emits circularly polarized radio waves (RHCP). Clover design provides an omnidirectional pattern. High efficiency of 99% transfers almost all power to the airwaves. Low SWR of 1.5:1 minimizes cable loss. You get a clear video signal over distances of up to several kilometers.
Technical characteristics and functionality
The Singularity 1280 V2 operates in the 1250–1290 MHz range. Central frequency 1300 MHz. Gain 1.9 dBic. Cross-polar rejection -15 to -30 dB. SWR (SWR) does not exceed 1.5:1. Radiation efficiency 99%. Axial ratio 1.0. Characteristic impedance 50 Ohm.
The antenna head size is 40.5 mm (diameter) by 22.5 mm (height). Total length 156 mm. Base (leg) length 100 mm. Weight 18 grams. Coaxial cable RG402 or RG316. SMA (True-SMA) connector.
The antenna is designed for long-distance FPV flights at a frequency of 1.3 GHz. Canadian quality guarantees stable operation in any conditions. Excellent cross-polar rejection eliminates ground reflections. Light weight does not overload the drone. High efficiency increases the range of reliable reception.
