This amplified network loaded DC blocked GPS splitter features one input and two output for spitting RF frequencies from 1.1 GHz — 1.7 GHz. It is designed to amplify and split the L-band frequency to multiple devices from a single antenna. In the standard configuration, the J1 port passes DC voltage from a connected device to the antenna or another device up from the splitter. The other port J2 is DC blocked and loaded with a 200Ω resistor to simulate antenna current draw which prevent alarm faults.
This amplified GPS splitter(EDMO# NALDCBS1X2)features one input and two outputs, N-type female connectors.
