These passive GPS splitters feature one input and two outputs for spitting RF frequencies from 1.1 GHz — 1.7 GHz. It is designed to passively 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 prevents alarm faults. This passive GPS antenna splitter (EDMO# ELDCBS1X2T) features one input and two outputs, TNC connectors; it also features EMI shielding.
