This variable gain GPS line amplifier features up to 30 dB of gain and an easy-to-use LCD display. This line amplifier is a one input and one output device that is optimized for GPS applications. The amount of gain can be changed using the control buttons, and the amount of gain is displayed on the LCD display. In the standard configuration, port J1 accepts DC voltage from a connected GPS receiver. This voltage is passed through to power an active antenna or other upstream device. In a networked (externally power) configuration, the output port (J1) is DC blocked, and a customer-defined output voltage is provided via the antenna port.
This variable gain GPS line amplifier(EDMO# NVGLCDLA-B)uses BNC connectors, 5-volt output voltage, 110-volt source voltage.
