Description
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. The other RF outputs (J2, J3, J4, J5, J6, J7 and J8) are DC loaded with 200Ω resistors to simulate antenna current draw to prevent antenna fault readings from connected GPS receivers.
