Product Description

The NLDCBS1X4 passive, networked GPS splitter has one input and four outputs and is based on the Wilkinson splitter design. The frequency response covers the entire GPS L-band (GNSS) frequencies with excellent gain flatness. In the standard configuration, without external power, RF output (J1) passes DC from the connected GPS receiver, through the splitter, and onto the antenna, while the other RF outputs (J2 - J4) remain DC blocked. When optional external power is applied, the DC output voltage on all RF outputs become user selectable. The DC blocked outputs incorporate a 200 resistor to simulate antenna current draw and prevent false antenna fault detections.

This passive, networked GPS splitter (EDMO# NLDCBS1X4S) includes one input and four outputs, each with SMA connectors. This GPS splitter operates on 9 - 32 VDC military DC connector and provides DC output of 5 volts.
