Description
The ALDCBS1X32 GPS Rack Mount Amplified Splitter is a one input, thirty-two output device with –
2dB max signal loss. 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 amplifier and roof antenna. The outputs are DC loaded with a 200Ω resistor to simulate the antenna current draw. This product is ideally suited for timing and testing applications where the GPS carrier signal is required by up to 32 GPS devices simultaneously.
