This low noise amplified GPS splitter features one input and four outputs for distributing filtered L1 GPS frequencies indoors with a nominal 0 db gain. A low noise input provides an excellent overall system noise figure. Padded outputs provide excellent port-to-port isolation and unity gain. Excellency frequency selection of the L1 band prevents interference from other high power radio sources. A five-volt power source connected on any of the RF output will power the splitter as well as an external GPS antenna. If multiple DC sources are connected then a ""pick and choose"" circuit will select one source to power the system, and the remain ports are switched to a 200Ω resistor to prevent antenna alarm faults.
This low noise filtered amplified GPS splitter(EDMO# LNFA1X4-T)has one-input & two-outputs, and has TNC connectors.
