Grounding and Lightning Requirements
Proper lightning protection requires tthe
he use of external primary protectors to complement the secondary
protection built into the PureWave equipment. The primary protectors offer the surge currents a direct
path to earth ground versus the undesirable “sneak” paths it may find through the equipment.
equip
Properly installed and grounded primary protectors will dramatically increase the surge withstanding
capabilities of the PureWave equipment. Surges that exceed the maximum ratings of the primary
protector devices will eventually cause them to fail, however these devices are generally designed to fail
short or open, as the application warrants, such that further surges will not damage the end equipment.
While a failed primary protector still results in a service outage, it does prevent further damage to the
more expensive end equipment.
A Base Station that is installed outdoor on the tower or mast (ODU) is especially vulnerable to lightning
surges. Good surge mitigation practice starts with the lightning rod and its connection to a proper sized
down conductor.
The ground down conductor should be as straight as possible and avoid incidental contact with other
conductors such that it represents the path of least resistance to earth ground from the lightning rod. The
tower/mast is also earth grounded to keep its conductive elements at earth potential (0V) for personnel
safety, and generally presents a less desirable path to ground to surge currents. ODU equipment and
external primary protection devices are mounted to the tower/mast and should be bonded to
t earth ground
at the same point on the down conductor. This practice is intended to avoid ground loop currents that may
flow from differences in potential between the tower/mast structure and down conductor while large surge
currents are flowing in them respectively.
espectively. Good surge mitigation practice also makes use of shielded
cables with peripheral shield grounding to minimize potentials induced on circuit conductors.
These cables should also be secured to the tower/mast at regular intervals to create physical separation
from conductors which are carrying surge currents. This practice avoids incidental contact or possible
insulation breakdown from high surge potentials.
A Base Station that is installed indoor units (IDU) requires similar protection as the outdoor installation
(ODU). Primary protection devices are installed on all cables just prior to entry of the facility and bonded
to an earth ground stake. Likewise, the cable shields are grounded at the entry panel which should be
bonded to the same earth
arth ground stake.
IDU equipment may also be vulnerable to surges entering via the AC power connection and steps should
be taken to install a proper AC Surge Suppressor device to complete a well protected installation.
3.1
Lightning Protection Installation Components
The following are considered to be the main elements that constitute the components of a lightning
protection scheme.

Figure 41, demonstrates
emonstrates graphically how these elements are applied to an overall lightning design.
Please note that this is simply a generic diagram and that each individual installation may have its own
specific requirements which may differ from the diagram. The key point to note is the overall concept.
The main items will be outlined in more detail in the following sections.
Figure 41 - A Typical Lightning Protection Design
3.2
Lightning Rod
The Lightning Rod must be welded to the mast structure and to a down conductor. This should be
constructed of a steel pointed tip and is in general installed at the highest point of the tower. It operates to
intercept the downward moving lightning strike by launching an upward going attachment spark. Once the
attachment is achieved, the bulk of the lightning current follows the ionized path. In this way, the lightning
rod diverts the lightning away from equipment on the tower.
If the lightning rod is not installed at the highest point on the tower, tthe
he equipment that is connected to the
highest point (usually a radio) is the most likely attachment point.
A Class I lightning rod (air terminal) is 3/8
3/8-inch copper or 1/2-inch
inch aluminum, while Class II calls for 1/21/2
inch copper or 5/8-inch
inch aluminum. Con
Conductor
ductor sizes vary accordingly, also depending on their composition
(stranded or strips) and materials (aluminum or copper). Since most soils contain acid or alkaloid
compounds that react with aluminum, any aluminum used must not come in contact with the soil.
so
Lightning rods (air terminals) 24 inches or higher should be used.
Quantum 1000 Base Station User Guide
Rev 1.1, Page 39 of 70
Referring to figure 41 above, the “Height Above Antenna” above the highest item of equipment (generally
the antenna) must be at least twice the distance (2 x d) between the outer surfa
surface
ce of the item and the
tower. This will ensure a “protection cone” of 60 degrees around the tower (30 degrees each side from
the lightning rod). In areas of high lightning activity, the “Height Above Antenna” should be increased to
up 5 times the distance.
3.3
Down Conductor
The purpose of the Down conductor is to provide the shortest and most direct path to the earth. The
grounding of the down conductor to earth must be of ground resistance no more than 5 ohms.
3.4
Co-axial
axial and/or Cat 5 Cable Shield Grounding
The purpose of the Shield grounding is to minimize the potentials induced on circuit conductors plus keep
the cable shields at earth potential (0V) for personnel safety.
All ground lugs must be properly bonded to the grounding system of the protected components
comp
along with
all Antenna cables. Prior to entry into any facility, the cables must be properly grounded to the building
primary ground system at the building entrance panel.
In case of an indoor installed Base Station then this will apply to the co
co-axial
axial cables that connect the Base
Station to the Antenna. This is because these co
co-axial cables provide the only inter-connection
connection between
the indoor and the outdoor.
In the case of an outdoor installed Base Station, then this will apply to the Cat 5 cab
cable
le and power
connection to the Base Station. In the case of an installation of the Base Station, it is the Cat 5 cable and
the power that provide the inter-connections
connections between the indoor and the outdoor.
3.5
Grounding and Bonding
The National Electric Code requires
equires that any accessible metallic surface of electronic equipment be
connected to earth ground for personnel safety. Earth ground connections are achieved by direct
connections to the AC power ground at the IDU and by a grounding lug on the ODU. A Craftsperson
Craft
must
attach a proper size wire to the ODU ground lug during installation, else the ODU chassis will float at
whatever potential appears at the shield connection of the coax.
3.6
Recommended Connection of a Bonded Ground
We will now examine the concept
pt of a bonded ground. Bonded connections for reliable, gas tight joints
between conductors require removal of all paint from both contact surfaces and holding them together
under high pressure such as with a bolt or screw. The use of toothed washers is al
also
so recommended to
cause the conductive surfaces to bite into each other for improved connectivity and eliminate movement
of the conductors due to vibration.

Rev 1.1, Page 40 of 70
3.7
Single Point Grounding Concept
Extensive analysis and investigation of installations has led to the belief that the root cause at the heart of
the majority of the failures is likely to be the presence of multi
multi-point
point grounding of equipment on the towers
and in the huts. Single point grounding these elements will eliminate ground voltage differentials and this
will dramatically increase the equipment survivability during surges.
Single point grounding requires that the grounding leads from the antenna, Base Station and Surge
Protection devices for a particular sector, are bonded together at the same point on the tower down
conductor. It is not necessary to bond all the sectors tog
together
ether but to ensure the components of any
individual sector have the same ground point on the tower.
In the equipment hut, in the event of an indoor installation of the Base Station then the chassis ground of
the Base Station and all the Surge Protection Devices grounds must be grounded at the same point (see
figure 42).
Figure 42 - Single Point Grounding Concept
It is important to note that the following ground guidelines are followed during installations:

Surge Protection devices generally connect to ground by using a ground wire. Cut any extra
ground wire length when finished connecting it to the single point earth ground
Never loop or coil up the ground wire, always connect it straight to ground.
A good earth ground impedance is less than 1.0 ohm.
Measure ground impedance at the point where the protector ground wire is connected and not at
the ground rod.
Avoid sharp bends. Connect the ground wire as straight as possible.
Connect the protector ground wire and equipment ground (both power g

ground) to a single common ground.
Make sure all connections are fastened securely and are tight.
Never install protectors during a storm and always follow your local safety codes.

3.8
Lightning and Surge Protection
PureWave recommends that Surge Protection Devices are installed to protect the Base Station.
For an indoor installation of the Base Station these “Surge Protectors” devices would be installed at the
entrance to the building that “houses” the Base Station (see fig
figure 43).
Figure 43 - Indoor Installed Base Station Relative to Position of Lightning Protectors
Such a device will provide protection to the Base Station in the event of a “surge event” entering the Base
Station through the RF port.
Two recommended devices are:
•
•
PolyPhaser Model AL-LSXM
LSXM-ME (see figure 44). This is a 2GHz to 6GHz in-line
line surge filter with a
DC block. This is a uni-directional
directional device.
Altelicon Model AL-NMNFB
NMNFB-9 (see figure 45). This is a DC to 6GHz in-line
line surge filter. This is a
bi-directional device.

Figure 44 - PolyPhaser Model AL

Figure 45 – Altelicon Model AL
AL-NMNFB-9 Surge Protector (with ground lug)
Care must be undertaken when installing the surge protectors. IIf the device is bi-directional
directional then it is
irrelevant as to the direction of installation. If the device is uni
uni-directional
directional therefore it must be installed to
ensure that the protected side of the surge protector is connected to the Base Station. In the case of the
Polyphasor the N-type
type male connection is connected directly to the Base Station output and the N-type
female connection is connected to the Base Station to Antenna cable. The male to female design of the
surge protector means that it is very diffic
difficult
ult to incorrectly connect. In addition it is recommended that a
ground wire is connected to the ground lug that is provided with the surge unit (see figure 46).

Rev 1.1, Page 43 of 70
Figure 46 - PolyPhaser Surge Protector Connected to Cable with Ground Cable Attached
Actual
al installation will depend upon the tower specifics. General tower installation practices would have a
large ground bar or plate just at the cable entrance to the building and the Surge Protectors would be
either attached directly or via the ground wire tto
o this plate/bar. Alternatively the Surge Protectors can be
directly attached to the Base Station and then appropriate ground connections can be made.
In the event that the Base Station Radio is installed outside then it is recommended to install the surge
protection unit(s) between the Base Station and the Antenna.

RF port.
It provides a mechanism to effectively “ground” together the Base Station, the RF surge protector
and the antenna.
In the case of an outdoor installation, it is recommended that suitable building entry surge protection is
considered
nsidered and the equipment installer may want to consider based upon individual installation
requirements.
Note: Please ensure that appropriate weather protection is applied to all outdoor Surge
Protection devices.
Surge protection devices for both the Cat 5 and the power connections to the Base Station are already
built into the unit. No further devices are required to protect the unit. In addition, for an appropriate fee,
PureWave provides a RF lightning surge protection kit. This includes the RF surg
surge
e protection devices and
a “ground bar” which acts as a means to ground all the devices. Please refer to figure 4

Weather Sealing
There are a range of commercially available weather protection “kits” that provide all the necessary
components in addition to full instructions on “how to” weather protect. A generic weather sealing concept
will be adopted rather than a specific one.

5.2
Connect to the Base Station
There are three RJ45 Ethernet ports to connect and hence access the Base Station.
RS232: This is the serial interface to the Base Station. This interface will be primarily used for “out of the
box” configuration and debug purposes.
E-NET
NET 1: This Gigabit Ethernet port provides the data traffic backhaul interface that should be connected
connecte
to the Service Provider’s network equipment. This port allows in
in-band
band management of the Base Station.
E-NET
NET 2: This Gigabit Ethernet port provides an out
out-of-band
band management interface. In addition, this port
can be used for daisy chaining to another bas
base
e station or to connect to an external device such as a web
Camera.
The procedure to connect to the Base Station is:
•
•
•
•
Terminate the antenna ports ANT 1 and ANT 2 as directed.
Connect and Power on the Base Station.
Connect a “straight” Cat 5 Ethernet cabl
cable between the E-NET
NET 1 port on the Base Station and the
directly to your PC or to your switch.
To get access to Base Station CLI (Command Line Interface) you will need the following
hardware that come with the install kit. These are as follows:
RJ45 cable.
DB9 male connector (Modem Adapter).
DB9 female to DB9 female adapter.
Optional: Serial to USB connector. Most laptop nowadays comes with USB connection instead of serial
connection. If your PC/laptop has serial connection then you won’t need this adapter. If not, then you will
need to get serial to USB adapter to access the BS CLI (figure 57).

4.
Debur the center conductor using the DBT-01 deburring tool.
5.
Flare the braid slightly and push the connector body onto the cable until the connector snaps into
place, then slide the crimp ring forward creasing the braid.
6.
Temporarily slide the crimp ring back, and remove the connector body from the cable to trim the
excess braid at the crease line, then remount the connector and slide the crimp ring forward until
it butts up against the connector body

7.
Position either the heavy duty HX
HX-4 crimp tool with the appropriate dies (.429” hex) or the CTCT
400/300 crimp tool directly behind and adjacent to the connector body, and crimp the connector.
The HX-4
4 crimp tool automatically relea
releases when the crimp is complete.
8.
Position the heat shrink boot as far forward on the connector body as possible, without interfering
with the coupling nut and use a heat gun to form a weather tight seal.

Ethernet Cat 5 Cable
Identifying the RJ-45 Cable Type
To identify the RJ-45
45 cable type, hold the two ends of the cable next to each other so you can see the
colored wires inside the ends, as shown. In a straight
straight-through
through cable, the colored wires are in the same
sequence at both ends of the cable.
through cable using Cat 5E, it is mandatory that you follow the 568-B
568 standard
When making a straight-through
shown below. Otherwise, you risk the possibility of damaging the equipment.
