STARF107 Dual Frequency GNSS Antenna L1 L2 GPS with Magnetic Base 40dB Gain IP67 Waterproof for Surveying

STARF107 GNSS Antenna Kit Why choose this antenna Multiconstellation reception for accurate positioning: receives GPS L1 and L2, BeiDou B1 B2 B3, GLONASS G1 G2, and Galileo E1 E5b to support professional surveying and mapping workflows. Reduced measurement error: a multifeed point antenna design aligns the phase center with the geometric center, minimizing antennainduced positioning errors. Reliable signal tracking in difficult conditions: gain and wide beam width maintain strong reception at low satellite elevation angles and enable satellite tracking under partial obstruction. Rugged field performance: ASA plus housing, IP67 waterproof rating, and wide operating temperature range provide longterm reliability for outdoor and mobile use. Key benefits and how it solves problems Improves measurement stability and accuracy by keeping phase center error to 3 mm or less, which reduces systematic error in precision surveys. Extends usable signal reception down to low elevation satellites thanks to the antenna pattern and an LNA with approximately 40 dB gain, enabling consistent fixes in urban canyons and near obstructions. Simplifies deployment with a compact, weatherproof enclosure and included magnetic base and 5 m cable for quick attachment to vehicles, machinery, or temporary poles.
