Global GNSS Timing Antenna

Overview

GNSS1-TMG-26NMS is a timing antenna from PCTEL / Amphenol designed for global satellite navigation reception. It supports GPS, GLONASS, Galileo, and BeiDou and is intended for precise timing and positioning installations. The part description indicates a 26 dB active antenna with L-mount and collar mounting hardware.

Why Choose This Part

This is a purpose-built active GNSS antenna rather than a generic receive antenna, so it is aimed at timing and navigation installations that need consistent satellite signal pickup. Multi-constellation support can improve availability in difficult environments and during poor sky visibility. The L-mount and collar mounting options make it practical for fixed outdoor or mast-mounted installs.

Applications

Getting Started

Start by placing the antenna with a clear view of the sky and routing the coax to a receiver that supports active GNSS antennas and the required bias power. Verify connector type, cable length, and receiver antenna power settings before installation. For best timing performance, mount it away from local RF noise sources and follow the antenna placement guidance from the receiver and installation documentation.
