Antenna power output

Applicable receivers:  BD990 | BD992 | BD992-INS

Each antenna connector can supply DC power independently. Each output is supplied by a dedicated boost regulator. The primary antenna regulator can switch voltage between 5.7 V to 7.6 V by using a GPIO to change the feedback and can source a maximum of 150 mAmps. Switching is done to select narrow or wideband filtering for MSS jam-immunity in capable Trimble antennas. The output antenna features a constant 5.7 V output. Each antenna has a PTC with a hold current of 200 mA, which limits the output current and provides short circuit protection.
