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. **Product Type:** GNSS Antenna ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDusYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a95037caff381fa17ffa9d8d51b96e55141f3c60/29691-GNSS-L1-L2-L-Bare-Antenna-BT-4815-150mm-Feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDvMYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--d38161417d2a5091f0961dbe09a9caaea79a25a5/29691-GNSS-L1-L2-L-Bare-Antenna-BT-4815-150mm-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDvsYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--6dbae1dac8d66a386b541944d02060ec3e7fab79/29691-GNSS-L1-L2-L-Bare-Antenna-BT-4815-150mm-Back.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDwMYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--2754d03a6178e138c60ba275977887ffa7bc21bd/29691-GNSS-L1-L2-L-Bare-Antenna-BT-4815-150mm-Scale.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
