RLACS354

Updated on May 12, 2026

The RLACS354 is a precision-tuned surface mount triple-band antenna that provides coverage for triple-band GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3,
Galileo-E1/E5a/E5b, BeiDou-B1/B2/B2a, NavIC-L5, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], plus L-Band correction services. It is especially designed for precision triple-frequency positioning.

This antenna provides superior multipath-rejection and axial ratio, a linear phase response, and tight phase centre variation (PCV), while protecting against intermodulation and saturation caused by high-level LTE 700 MHz signals. It is housed in a magnetically mounted, IP67 weatherproof enclosure.


  • Very low noise preamp (< 2.5 dB typ.)
  • Low axial ratio (< 1.5 dB at zenith)
  • Tight phase centre variation
  • High-gain LNA (37 dB typ.)
  • Low current (45 mA typ.)
  • ESD circuit protection (15 kV)
  • Invariant performance from 2.5 to 16 VDC
  • IP67, REACH, and RoHS compliant


  • Excellent interference mitigation
  • Excellent multipath rejection
  • Increased system accuracy
  • Excellent signal-to-noise ratio
