Cisco 4G Indoor/Outdoor Active GPS Antenna

Designed to deliver rock-solid satellite timing for Cisco networks, the Cisco 4G Indoor/Outdoor Active GPS Antenna (GPS-ACT-ANTM-SMA) is a versatile solution built to optimize GPS reception for critical network infrastructure. This active GPS antenna is purpose-built to connect with Cisco 819 Integrated Services Routers (ISRs) and Cisco 4G Enhanced High-Speed WAN Interface Cards (EHWICs), providing a reliable feed of GPS broadcasts from satellites. Whether deployed inside the building or out in the elements, this antenna is engineered to help your network maintain precise timing, improved synchronization, and dependable location services. With a focus on robust performance in varied environments, it’s a smart choice for data centers, branch offices, and remote sites that demand consistent GPS timing without compromise.

• Seamless integration with Cisco 819 Integrated Services Routers (ISRs) and Cisco 4G Enhanced High-Speed WAN Interface Cards (EHWICs), enabling satellites to deliver accurate GPS timing directly to your core network devices. This compatibility ensures smooth deployment in existing Cisco environments and minimizes configuration complexity, so you can achieve reliable timing fast.
• Active GPS design with a built‑in low-noise amplifier (LNA) that boosts weak satellite signals and improves reception in challenging environments. The active circuitry helps maintain stable GPS timing even when the antenna is placed near obstructions, windows, or inside structures, delivering dependable performance where passive antennas may struggle.
• Indoor/outdoor versatility with a weather‑resistant form factor that supports multiple installation scenarios. Whether mounted on a building exterior, a rooftop, a wall, or a ceiling, the GPS-ACT-ANTM-SMA provides flexible placement options to maximize satellite visibility and optimize signal strength for your network timing needs.
• Compact SMA connector (GPS-ACT-ANTM-SMA) designed for secure, reliable connections to Cisco equipment, minimizing signal loss and ensuring a dependable link between the antenna and the GPS input on Cisco devices. The connector type supports easy cabling and maintenance without sacrificing performance.
• Enhances network performance through precise GPS timing that improves synchronization across devices, which can translate to more accurate call routing, better data throughput, and tighter security synchrony. By providing consistent satellite timing, this antenna supports critical operations such as time-stamped logging, event correlation, and coordinated network actions across distributed sites.

How to install Cisco 4G Indoor/Outdoor Active GPS Antenna

• Plan placement for optimal satellite visibility: choose a location with a clear view of the sky, away from dense metal structures or large obstructions that could block GPS signals. For outdoor installs, mounting on an elevated, unobstructed surface yields the best signal quality, while indoor placements should minimize metal interference and maximize line-of-sight to satellites.
• Mount the antenna: use the appropriate mounting hardware to secure the antenna to an exterior wall, roof edge, or interior mounting point. Ensure the housing remains weather-protected when installed outdoors and that cabling has a safe, compliant path to the Cisco device.
• Connect the antenna to the Cisco device: attach the GPS antenna’s SMA connector to the GPS input on the Cisco 819 ISR or the corresponding slot on a Cisco 4G EHWIC. Use a quality coaxial cable with minimal length to reduce signal loss, and avoid sharp bends or kinks in the cable.
• Power and bias considerations: if the active GPS antenna requires external power, supply the appropriate bias or power according to Cisco’s guidelines. If the device can power the antenna through the connection, ensure the device’s settings enable this feature and verify that the antenna is receiving power.
• Verify GPS lock and timing: once connected, access the Cisco device’s management interface to confirm a satellite lock and stable GPS timing. Check the GPS status indicators, log entries, or timing metrics to validate synchronization accuracy and adjust placement if necessary to optimize performance.
