Military High-Isolation Amplified Networked 1x4 GPS Antenna Splitter | 1-input & 4-outputs, TNC Connector
Product Description
This Military Qualified High-Isolation amplified network loaded DC blocked GPS splitter features one input and two outputs for spitting RF frequencies from 1.1 GHz — 1.7 GHz. Each output port (J1–J8) is isolated from external signals to prevent interference. In the standard configuration, the J1 port will pass DC voltage from the connected device and pass power to an antenna or other devices. Ports J2–J8 are DC blocked and loaded with 200Ω resisters for preventing alarm faults. Mil-Specs splitters are qualified to rigorous MIL-STD 810F environmental & MIL-STD-461F EMI standards.
This Mil-Spec amplified, high-isolation GPS amplified splitter (EDMO# MILNHIALD4) includes one input and four outputs each with TNC connectors, 5-volts network option, and a military DC connector that uses DC voltage from 9–32 VDC.
