GPS 1x4 Military Qualified Splitter (MS14GT)

GPS 1x4 Military Qualified Splitter (MS14GT)Designed for all GNSS frequencies, the MS14GT is a military qualified 1X4 GNSS splitter that makes it possible to use a single GPS referencing antenna to evenly distribute GPS GNSS signals to up four devices receivers simultaneously. Designed for ruggedized applications, the MS14GT is qualified to a wide range or MIL STDs. The MS14GT features an antenna DC bias select circuit. This allows for the active antenna DC input from devices connected to any

Designed for all GNSS frequencies, the MS14GT is a military qualified 1X4 GNSS splitter that makes it possible to use a single GPS referencing antenna to evenly distribute GPS/GNSS signals to up four devices/receivers simultaneously. Designed for ruggedized applications, the MS14GT is qualified to a wide range or MIL-STDs.

The MS14GT features an antenna DC bias select circuit. This allows for the active antenna DC input from devices connected to any of the four outputs be applied to any or all RF outputs. With this feature, one DC voltage will be chosen to power the antenna while others will be switched to DC loads which will prevent any antenna alarm faults from connected devices. Designed for redundancy, if the selected DC bias input should fail (or the device is disconnected), the DC bias will automatically switch to another DC input to ensure an uninterrupted supply to the active antenna and maintaining GPS lock at all of the other devices.

• Optimum signal quality with low noise and balanced gain
• Designed to support rugged, reliable, trouble-free deployment
• DC bias select automatically switches port if selected DC bias input fails
• MS14GT is standard configured with high isolation (does not require unused outputs to have 50 ohm terminations)
• Standard configurations includes N(f), SMA(f), and TNC(f) connectors

Key Features

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.
