Raven offers two GPS signal splitters: Bias T A bias T takes 1 signal from the antenna and splits up the gps and beacon signals. The antenna cable is connected to the bias tee (BT-0) which splits the signal and provides two signal outputs. One output connects to the MRB-2A beacon receiver and the other connects to your GPS receiver. All connection on the bias tee are TNC. A bias T may be used with the combined GPS/Beacon antenna (MBA-2 & AMBA-4). GPS Splitter The BT-2GPS splitter takes a single antenna input and splits it between two separate ports. Voltage is applied through the primary port to the GPS antenna. The secondary port provides a signal for a second receiver. All connections on the GPS splitter are TNC. A unique feature to this product is its capacity to pass low frequency beacon signal out both ports. No matter what your operating environment--Marine, aviation, or land--Raven's rugged components are built to last.
