Description
The RMALDCBS1X8 GPS Rack Mount Amplified Splitter is a one input, eight output device. The
frequency response covers the GPS L1 & L2 bands with excellent gain flatness. In the normal
configuration, the splitter is powered by a transformer that supplies power to the splitter’s amplifiers and
roof antenna. The outputs are DC loaded with 200Ω resistors to simulate the antenna current draw.
Product is ideal for timing and testing applications where the GPS carrier signal is required by up to 8
GPS devices simultaneously.
