Hello, Perhaps I’m missing something obvious but I haven’t been able to find an explicit statement whether or not the USRP B205mini-i receiver has a bias-T to supply power to an active antenna. Does anyone know whether it does, and if so how to enable it and its specifications? If it does not, does anyone have any recommendations for a good value bias-T, ideally small and without needing a separate power supply (which would defeat the convenience of a bus-powered device). This is for use with a L1 (1,575 MHz) active GPS antenna which needs 2.3–5.5V 16.6mA. Thanks in advance! Best wishes, Steven

There’s no built in bias tee for the RF ports on any USRP. For USRPs with GPS antenna inputs, those inputs have a 5V bias on them.
