{"title":"BT-3710 GNSS L1/L2/L-Band Survey Antenna with 150mm U.FL Cable","handle":"gnss-l1-l2-l-embedded-surveying-antenna-150mm-u-fl","url":"/products/gnss-l1-l2-l-embedded-surveying-antenna-150mm-u-fl","description":"This high-performance multi-band GNSS antenna is designed for applications that need high accuracy and continuous operation. It supports GPS, GLONASS, BeiDou and Galileo constellations across multiple frequency bands, plus L-band correction services.Built to outperform standard patch antennas, it captures and amplifies satellite signals before feeding them to your GNSS module through an integrated 150 mm coaxial cable with a standard IPEX (U.FL) connector.The BT-3710 is housed in a secure 119.9mm enclosure for dependable field deployment, with an operating temperature range suitable for harsh outdoor environments.Features:Multi-Band & L-Band Support: Full compatibility with GPS L1/L2, GLONASS L1/L2, BeiDou B1/B2/B3, Galileo E1/E5b, and L-band signals ensures maximum satellite availability and support for real-time correction services like PPP and u-blox PointPerfect.High-Gain Signal Amplification: A high passive gain of 5.5 dBi is paired with an integrated 40 dB low-noise amplifier (LNA) to ensure a strong and reliable satellite lock in obstructed environments, such as urban canyons or under foliage.Survey-Grade Accuracy: Achieves a highly stable phase center with an error of just ±2mm and maintains a low noise figure (≤2 dB), making it ideal for applications requiring centimeter-level precision.Specifications:Frequency range: 1164 – 1610 MHzPassive gain: 5.5 dBiLNA gain: 40 ± 2 dBNoise figure: ≤ 2 dBVSWR: ≤ 2.0Impedance: 50 ΩCable: 150 mm, 1.13 mm diameterConnector: IPEX (U.FL)Dimensions: Ø119.9 mm × 16.2 mmWeight: 190 gOperating temperature: -40 °C to +85 °COperating humidity: 40–95%Suitable for professional GNSS, surveying, robotics and positioning builds where a compact embedded antenna and U.FL connection are required.","vendor":"SparkFun","product_type":"GNSS Antenna","in_stock":true,"options":[],"variants":[{"id":16180,"title":"Default Title","sku":"SF-GPS-29691","mpn":"GPS-29691","price":294.95,"on_sale":false,"in_stock":true,"available_quantity":41}]}
