## Description

The BT-T009 is a compact, lightweight multi-band GNSS helical antenna supporting L1, L2, and L5 frequencies across GPS, GLONASS, Galileo, and BeiDou constellations. Designed for permanent mount applications with a four-screw installation for tamper resistance. Weighs just 22g with a standard SMA connector. L5 is the third civilian GPS signal, designed for high-accuracy applications. When used in combination with L1 and L2, the triple-band configuration provides a highly robust positioning service. Best suited for installations with a clear view of the sky. Key Features Multi-Band GNSS – Supports L1, L2, and L5 frequency bands Multi-Constellation – GPS, GLONASS, Galileo, and BeiDou Helical Design – Compact form factor for permanent installations Tamper-Resistant Mounting – Four-screw permanent mount design SMA Connector – Standard SMA interface Lightweight – ≤22g Ideal For High-precision GNSS positioning systems Permanent outdoor GNSS installations Multi-band RTK receivers Surveying and mapping equipment Package Contents 1× BT-T009 GNSS Multi-Band Helical Antenna (SMA) Note: Verify that your GNSS receiver supports L1, L2, and L5 signals to take full advantage of this antenna's multi-band capability. Standard single-band receivers will only use the L1 signal. Resources BT-T009 Datasheet
