Antenna Ports OUT
The EU has two duplex 4.3-10 female antenna ports
for transmitting and
receiving signals to and from distributed antennas. These RF ports can be connected
directly to antennas (i.e. using RF jumper cables) or through splitters, allowing
additional antennas to be fed by the EU.
Antenna Ports IN
The EU has two duplex 4.3-10 female antenna ports
for connecting the antenna
OUT ports of two ION-U L 7/80-85/17(E)P/19P. These ports can also be used for
connecting the antenna OUT ports of a second EU such as the EU L 23/23 to add an
additional band. The signals are combined and fed to the RF antenna OUT ports of the
EU L 25T/25T.
