Attenuators are used to attenuate the signal levels from the antennas. The locations of
the attenuators and the types of attenuators used are determined by the ND&I team for
each site installation.
Installing an attenuator here

Installing an attenuator here
attenuates all antennas
connected to the splitter.
Power supplies and bias tees are used to power the active antennas and amplifiers
used as part of the antenna system. The number of power supplies used and their
location is determined by the ND&I team. If emergency power is available, the power
supplies are installed on emergency power. Use the power supply/bias tee mounting
bracket to mount both devices to the splitter board to reduce the area needed by each
device.

To mount a power supply and bias tee use the Bias Tee and Power Supply
