Rack Mounting
NUs, HUBs and CUs may also be secured to vented (perforated) IT rack shelves. Please
make sure that your shelf is adequately vented (unit operating temperature is available on the
WAVE Portal).
b. Connecting Donor Sources to the NU
The QUATRA EVO NU has two independent N-type(f) RF ports for connecting off-air antennas
or small cell donor signals. Please connect your donor cables according to the Single or Dual
Operator Mode you intend to use (see the illustrations below).
NOTE
Small cell and off-air inputs may be used in the same system, but not for the same donor port.
NOTE
Once the donor source cables are connected, you will use the WAVE Portal to configure the
ports for Single or Dual Operator Mode, select your operator(s), and select Small Cell Mode for
any port that is to be fed with a small cell signal. These configuration options are described
later in this manual.
Cellular Donor Antenna Input
The donor antenna is used to collect the donor signal from the external (over-the-air) operator
network. Better donor signals lead to better customer experiences, improved voice quality and
data throughput. A signal-to-noise ratio (SINR) of > 5 dB is strongly recommended for each
given operator’s source signal, however lower quality signals will work if that is all that is
available for the site. Better SINR leads to better throughput and “bars” of signal strength on
cellphones.
Each donor antenna should be mounted safely and securely where it can access the desired
cellular network, with a clear unobstructed view of all candidate cell sites. Donor antennas
should be mounted a few feet above the roof or roof-edge walls (minimum), at least 12 inches
