[Discuss-gnuradio] Feeding 12VDC through COAX using DBSRX

[Patrik Tast]

Hi All,

 

At the moment I feed 12 VDC into COAX outside Ettus USRP1 12VDC to power my LNA. I have a DC-Block

at the receiver to prevent voltage back into the DBSRX-LF REV 2.2.

 

Connector J100 say Antenna Bias + and GND 500mA @ 6V.

 

My question is, is it possible to feed 12V to the J100 without damaging the unit(s)?

 

Thanks,

Patrik
