The Telestream SPG9000-ACC-ANT Upgrade: Multi-GNSS Dual-Band Rooftop Antenna allows for integration with the GNSS Receiver with the user's SPG9000 Timing/Reference Generator. This accessory requires the SPG9000-GNSS Software License (not included) and a coaxial cable with a type-N connector (not included) for full usage. The antenna allows the user to synchronize the instrument's timing to one or more GNSS (Global Navigation Satellite System) signals such as GPS, GLONASS, BeiDou, Galileo, and QZSS along with the L1 and L5 frequency bands. This accessory supplies the unit with a standard GNSS RF signal for the ability to use the GNSS system's stable frequency reference.

This option is field-upgradable and can be purchased at any time for usage with the SPG9000 Timing/Reference Generator.
