power, or too much signal power from too many interfering cell sites. In this case, your best
option may be a small donor antenna mounted closer to the street level where the operators
have optimized their networks to serve pedestrians.
Please watch the Webinar video on donor antenna practices. Good signal quality in means
good signal quality out. Once you become good at donor antennas, you become a great
installer.
Case Studies and videos to help you learn more about antenna selection are available in the

Useful Toolbox Items for Installs
We recommend that you bring the following items to every installation. Because every site is
different, and you often won’t know what you need until you begin the installation.
2x6ft Ethernet cables (machine made)
If a CU cable is alarming, you can use the cables
to connect the CU directly to the NU to verify it is
functioning properly. Then troubleshoot the CU
cables.
N Attenuators (10 and 20 dB values)
Use to attenuate an extremely strong donor
signal, which might cause the signals to not be
relayed with good SINR, or with the gain needed
for full DL power. NOTE: Some global operators,
and the FCC, have rules to reduce gain if a donor
signal is too strong.
2-Way and 3-Way splitters, N type(f)
connectors
Splitting donor signals to multiple NU ports if
needed.
Various short N-N type cables and
barrels
Misc. connection needs.
SMA(m) Cellular antenna Spare for the NU modem.
10dB coupler and N(m) to SMA(m)
cable
If no signal is available at the NU CELL modem
port, you can use the coupler to connect the CELL
port to one of the donor coaxial feeds.
LPDA-R, Wideband Directional, whip,
and larger and smaller Panel antennas.
Donor antenna options. Highly directional (narrow
beam) antennas are usually best, but if the best
quality donor signal is closer to street level, you
may want a panel antenna, or even a small whip
antenna (stealth).
