Vesper Marine GA38 External GPS/GLONASS Antenna for Cortex V1 / M1 (VES-010-13305-00)
Maximize the positioning accuracy of your Vesper Marine system with the GA38 External GPS/GLONASS Antenna (VES-010-13305-00) — Vesper’s dedicated high-performance active antenna designed specifically for the Cortex V1 Class B AIS transponder with integrated VHF radio and the Cortex M1 handheld VHF. When installed in an optimal location with a clear sky view, the GA38 delivers faster satellite acquisition, improved position accuracy, and more reliable GPS lock compared to relying on an internal antenna alone.

- Active Antenna with Built-In LNA – Integrated low-noise amplifier boosts weak satellite signals, enabling reliable position lock even in partially obstructed environments
- Improved AIS Position Accuracy – More accurate GPS data means your vessel’s AIS position broadcasts are more precise, improving safety and situational awareness for other mariners
