Connector Type BNC
Vdc Bias 12 Vdc @ 150 mA
NOTE: The RF distribution circuitry is activated only if connected to an RF input that
has 12 Vdc bias.
Each UR4+ RF antenna input port provides 12 Vdc bias @ 150 mA. The 12V dc
bias is present only when the UR4+ receiver is powered on. Therefore, if a cascaded
UR4+ Receiver is powered off, the RF signal will not appear in the UR4+ receivers
that follow the powered-off receiver.
