4.9.3 Powering an antenna or antenna splitter
Provision of 24 VDC power to an FS II antenna is done as follows:
• Connect the antenna to a 150/UNI-DIN power supply unit through the 4-pin
DIN connector at the antenna.
• Connect the antenna to an antenna splitter which is powered by a power-
supply unit.
The preferred method is to connect the antenna to a powered antenna splitter, as
illustrated in Figure 4-9 Powering an antenna splitter . An antenna splitter
distributes power to all antennas connected to it. A single power-supply unit can
power the maximum 5 antennas. However, maximum cable lengths will be
reduced.
