Description
The Hercules MA131 is a rugged 2-in-1 external antenna solution that combines satellite navigation and 915 MHz ISM-band connectivity in a single low-profile housing. It is designed for reliable performance on vehicles and outdoor assets, supporting tracking and monitoring systems that need consistent positioning and robust wireless links.
- 2-in-1 combination design: Supports GNSS reception and 915 MHz ISM-band operation in one compact antenna.
- Built for harsh environments: Rugged polycarbonate enclosure designed to withstand impact and outdoor hazards.
- Improved GNSS reliability: Optimized to track multiple satellite constellations, helping maintain location performance in challenging environments such as dense urban areas.
- Interference resilience: Integrated front-end filtering helps protect GNSS performance near out-of-band transmissions.
Typical use cases: asset tracking, remote monitoring, vehicle telematics, and outdoor equipment connectivity.
