Dual-Band GNSS Anti-Jamming Antenna B1/L1/E1 B2a/L5/E5a 16-Element 15-Source Suppression Dual Output

Product Introduction

          The YT340 Dual-Band Anti-Jamming Antenna is a 16-element dual-band GNSS array that receives 16 channels of B1/L1/E1 and B2a/L5/E5a signals and outputs both bands after anti-jamming processing. It suppresses up to 15 wideband interference sources on each band, with a B1/L1/E1 receive bandwidth of 1568±10 MHz and a B2a/L5/E5a receive bandwidth of 1176±8 MHz, delivering high integration and high performance.

          The antenna array offers VSWR ≤2.0, right-hand circular polarization (RHCP), 0360° azimuth and 090° elevation coverage, and a peak gain of ≥2.0 dBi.

          The LNA provides 25 dB±1 dB gain, ≤2.5 dB noise figure, ≥50 dB out-of-band rejection at f0±50 MHz, and a 10 W RF input power limit. L1 and L5 anti-jamming performance: ≥110 dB against a single interference source and ≥90 dB against 15 sources, with an antenna output power of -55 to -75 dBm.

          The unit runs on +20~32 V (28 V default) with <70 W power consumption, measures 340×340×65 mm, weighs ≤5 kg, and is finished in grey.

           It uses an MS3112E14-19P power/I-O connector and separate TNC-KF RF outputs for B1/L1/E1 and L5. Operating range is -40℃ to +70℃ (storage -40℃ to +85℃) — ideal for large unmanned platforms, surveying, marine and critical-infrastructure timing applications requiring high-precision positioning.

Key cores 

1. 16-element dual-band array: Receives 16 channels of B1/L1/E1 and B2a/L5/E5a signals with independent anti-jamming processing per band.
2. 15-source suppression: Suppresses up to 15 wideband interference sources per band for stable positioning under strong interference.
3. High suppression capability: L1/L5 rejection of ≥110 dB single-source and ≥90 dB against 15 sources.
4. Dual RF output: Separate TNC-KF outputs for B1/L1/E1 and L5 for easy multi-system integration.
5. Wide-angle, high-gain coverage: 0360° azimuth and 090° elevation, ≥2.0 dBi peak gain, RHCP.
6. Low-noise, high-gain LNA: 25 dB±1 dB gain, ≤2.5 dB noise figure, ≥50 dB out-of-band rejection at f0±50 MHz.
7. High integration, high performance: Array, anti-jamming and RF channels designed as one unit.
8. Low power draw: +20~32 V input (28 V default) with <70 W consumption.
9. Industrial-grade reliability: -40℃+70℃ operating and -40℃+85℃ storage, MS3112E14-19P rugged connector, 340×340×65 mm, ≤5 kg.
