Depending on the number of AOA panels used, not all ports need to be connected.
Where both TDOA and AOA are employed at the same site, attenuators are required at the
TDOA inputs to the switch to compensate for the added gain of the RFDU. See Figure 2-9.
In installations utilizing the dual-band combiner, connect input cables from the individual band
multicouplers to the appropriate input ports on the combiner. Connect the dual-band combiner
output ports (A1 SUM OUT, A2 SUM OUT, etc.) to the corresponding WLS antenna input ports as
shown in
Figure 2-10.

Note: Different AOA antenna versions may have different labeling. Ports may be labeled using
the nomenclature OL (Outer Left) or as Port 1. Figures are shown for each case.
