Optional Installation External Hybrid Combining Unit (EHCU)
4.
Start to apply the
self-amalgamating (self-fusing)
tape approximately 50 mm
below the lower edge of each
connector. Overlap each turn by
50%. Proceed all the way up to
the edge of the splitters.
Vary the stretching of the tape
and avoid spaces.
5.
Apply two, half-overlapped,
slightly-stretched layers of
electrotape. For each layer,
start 30 mm below the lower
end of the self-amalgamating
(self-fusing) tape and proceed
all the way up to the edge of the
splitters.
5 Optional Installation External Hybrid
Combining Unit (EHCU)
The RRU-N should be equipped with EHCU to achieve the combined
configuration. The EHCU can be ordered as an optional part.
Note: The antenna system must have been tested. For more information, see
Verifying Antenna Systems, 1/1532-LZA 701 0001.
This section describes how to install the external EHCU on a pole or mast and
how to connect the cables.
