GNSS1-TMG-40N

Overview

The GNSS1-TMG-40N is a high-performance active GNSS timing antenna designed for carrier-class synchronization applications. It provides 40 dB of gain and supports multiple constellations including GPS L1, GLONASS L1, Galileo E1, and BeiDou B1. The rugged housing and integrated lightning protection make it ideal for permanent outdoor installations in telecommunications and power grid infrastructure.

Why Choose This Part

This antenna features a high-gain 40 dB low-noise amplifier (LNA) to compensate for long coaxial cable runs typically found in tower or rooftop installations. It includes integrated transient voltage suppression, ESD protection, and reverse polarity protection to ensure high reliability in harsh environmental conditions. The narrow bandwidth filtering provides excellent out-of-band rejection to prevent interference from nearby cellular transmitters.

Applications

Getting Started

Installation requires a clear view of the sky and a 50-ohm coaxial cable terminated with an N-type male connector. The antenna is powered by a DC bias (2.8V to 9V) typically provided by the GNSS receiver's RF input port. Ensure the mounting location is grounded to utilize the internal lightning protection effectively.
