GPS 1x4 Military Qualified Splitter (MS14ISO)

GPS 1x4 Military Qualified Splitter (MS14ISO)The MS14ISO is a military qualified, one input four output GPS splitter with a MIL STD 704F compliant isolated power supply. A typical application involves an input from an active GPS antenna that is split evenly between four GPS receivers devices. The MS14ISO is standard configured to accept external DC input via the included 3 pin D38999 Mil DC power connector. The RF outputs, J2, J3, J4, and J5, are DC blocked standard and feature a 200 ohm DC load

The MS14ISO is a military qualified, one-input four-output GPS splitter with a MIL-STD-704F compliant isolated power supply. A typical application involves an input from an active GPS antenna that is split evenly between four GPS receivers/devices. The MS14ISO is standard configured to accept external DC input via the included 3-pin D38999 Mil DC power connector. The RF outputs, J2, J3, J4, and J5, are DC blocked standard and feature a 200 ohm DC load to simulate an antenna DC current draw for any receiver connected to that port.

About Our Military GPS Splitters

GPS Source splitters are deployed across defense programs because they deliver exceptional GNSS distribution without compromising signal quality. The foundation of every GPS splitter military grade model is precise RF engineering, ensuring:

High Isolation Across Outputs
Prevents interaction between receivers, reducing interference risks and protecting sensitive electronics.

Controlled Gain & Loss Management
Maintains signal power within tight tolerances across all ports—critical for timing accuracy and navigation precision.

Impedance Matching & Low Noise Architecture
Minimizes reflection, reduces noise, and safeguards signal fidelity even in complex installations.

Advanced Fault Detection (Selectable Models)
Some rugged GPS splitter units offer port monitoring to detect antenna failures, cable faults, or power disruptions in real time.

Flexible Powering Options
Flexibility allows seamless integration with a variety of military GNSS system architectures. Choose from:

• DC pass-through
• External power inputs
• AC/DC configurations
• Redundant power setups
• DC-blocking versions

Designed for Harsh and Variable Environments
Military operations demand equipment capable of withstanding environmental extremes—desert heat, arctic cold, field vibration, high shock loadouts, and electromagnetic exposure. Our MIL STD splitter devices are engineered specifically for:

• Extreme temperature swings
• High humidity and moisture exposure
• Vibration and shock typical of ground, air, and naval platforms
• Electromagnetic interference common to tactical environments
• Constant operational uptime under heavy load

We build rugged GPS splitter product designed for real-world duty cycles—not controlled lab settings. With GPS Source, you gain hardware that survives and performs in the environments your mission demands.
