to the splitter can be powered at a distance of up to 300 meters (900
feet); beyond that distance they will need to be locally powered.
Note: To use the system with cable lengths over 200m the
software update in release 1.5.6 or better must be installed
on the basestations.
POWERING AN ANTENNA OR ANTENNA SPLITTER
Provision of 24 VDC power to a CellCom antenna is done in one of
three ways:
• 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.
• Connect the antenna to a CellCom basestation’s “transceiver” RJ-45
connector.
The preferred method is to connect the antenna to a powered antenna
splitter, as illustrated in Figure 4-8. An antenna splitter distributes
power to all antennas connected to it. A single power-supply unit can
power the maximum 10 antennas. However, cable lengths will be
reduced.
