GPS NETWORKING's ALDCBS1X2 GPS splitter (GNSS splitter) is a one input, two output amplified splitter based on the Wilkinson splitter design. The frequency response covers the entire L-band (all GNSS frequencies) with excellent gain flatness. In the standard configuration, (J1) passes DC from the connected GPS device through the splitter to the input (antenna port). The other RF output (J2) is DC blocked and loaded with a 200 Ohm resistor to simulate the antenna current draw to prevent false antenna alarm faults.
