Product Description

Meinberg's GNMANTv2 is a multi-GNSS, multi-band antenna that is engineered and manufactured entirely by Meinberg from the ground up to ensure optimum performance for timing & synchronization applications.

The GNMANTv2 provides dual-band reception with excellent reception of all GNSS constellations (GPS, GLONASS, Galileo, BeiDou), encompassing almost all services in these systems. Additionally, the antenna supports reception of augmentation systems, including SBAS, Fugro AtomiChron®, and QZSS. The GNMANTv2 also features a dedicated narrowband frontend filter for effective rejection of out-of-band signals and a very low-noise preamp, allowing for maximum signal quality with minimal interference. Integrated surge protection helps to protect the antenna from damage from surge voltages and indirect lightning strikes.

Housed in an injection-molded ABS IP65 plastic case with Meinberg's distinctive waterproof 'mushroom' design and specified for operating conditions from -70 °C to +85 °C, the GNMANTv2's construction helps it to withstand the rigors of outdoor use in even the most challenging weather conditions.

The GNMANTv2 is optimized for use with Meinberg's GNS, GNM, and GXL clock technologies, including LANTIME, IMS, and microSync time servers, as well as Meinberg's standalone multi-GNSS receivers.
