CU Placements
NETWORKED SMART BOOSTER 6
Off-Air Donor Coverage Units Where Needed
For Off-Air installs, mount Coverage Units where the
macro network does not reach. Example, if a
100,000 ft
2
warehouse only lacks service in a few
locations, then only use CUs in those locations.
Small Cell Donor Contiguous Coverage Units
For Small Cell donor configurations, mount the CUs
to create continual coverage to ensure all areas
benefit from the added small cell capacity.

Cables and
Antenna
OPTIONAL: CU External Antennas
CUs contain internal omnidirectional MIMO antennas, and they are also equipped with external antenna ports in
the event that directional antennas are desired, or if the signal needs to be split to feed multiple service antennas
(splitter and cable losses will result in lower transmit power at the service antennas).
If external antennas are desired, place and mount the external antennas
according to the antenna manufacturer’s instructions and connect to the
RF ports on the back of the Coverage Unit.
Ask your QUATRA supplier
about antenna cables.
IMPORTA NT
• For best performance, mount the CU in an elevated position in open space.
• CU faceplate LEDs should be clearly visible.
• Off-Air Only: For maximum CU transmit power, do not mount CUs close to the NU antenna or the
CU may reduce its transmit power to prevent RF feedback.
