GPS Antenna Splitter – Diplexer
The Navtech Systems GPS diplexer NTS-DP1 enables two GPS receivers to share a single antenna. Using a combined low noise amplifier and power by-pass circuitry, the GPS antenna will supply amplified GPS signals to one or both receivers connected to the outputs.Antenna power supplied by either GPS receiver is by-passed to the antenna, to enable active antennas to be used as the primary signal source on any GPS installation.
By simply inserting the GPS diplexer in the antenna feeder cable, using standard TNC connectors, the GPS signal is correctly terminated, amplified and split to the respective receiver.
