The ALDCBS1X8 GPS Amplified Splitter is a one input, eight output device with 13dB minimum gain. The frequency response covers the GPS L1 & L2 bands with excellent gain flatness. In the normal configuration, one of the splitter RF outputs (J1) passes DC from the connected GPS receiver through the splitter to the antenna, allowing the GPS receiver to power both the antenna and the splitter’s amplifier.
