2 Site Planning
2.1 General
Before the start of any installation, a survey of the planned deployment site should be conducted.
The surveying personnel should be fully familiar with the details and requirements needed to
successfully install the GB-X10 radio system.
2.2 Equipment Checklist
The following lists suggested equipment the site survey team may require:
•Binoculars (not always required)
•WAAS-capable GPS location device
•Tape measure to determine distances for cable runs to ingress points
•Digital camera (not always required)
•Site survey report form to document and help assess site
•Signaling mirror (not always required)
2.3 Line of Sight
The GB-X10 80GHz Wireless Gigabit Ethernet link requires Line of Sight (LOS) for proper
operation. Binoculars and spotting mirrors may be used to assist in the confirmation of LOS.
Path planning should include an investigation into future building plans that could block the LOS
path and other long-term incremental obstructions, such as tree growth. Intermittent obstructions,
such as aircraft at a neaGB-X10y airport, should also be considered.
The following table lists near-field distances.
Table 2.3-1: Near-Field Distances
Frequency/Antenna Low Band High Band
80 GHz 1 ft. (30 cm) 17.84 ft. (5.43 m) 20.30 ft. (6.18 m)
80 GHz 2 ft. (60 cm) 71.36 ft. (21.75 m) 81.20 ft. (24.75 m)
The following table details the minimum F1 (First Fresnel) clearance required from obstacles in
order to ensure the radios will operate properly.

2.4 Link Distance
Measurement of the link distance is important in estimating the link availability and calculating the
expected Receive Signal Level (RSSI). This measurement can be performed using the latitude and
longitude coordinate readings from a Global Positioning System (GPS) device, which is placed near
the proposed locations of the antennas. Additionally, a GPS reading will be required in order to
comply with the FCC registration process.
The minimum link distance is dependent on the antenna sizes used along with the minimum allowed
transmit power of 2dBm, so as not to exceed the maximum received signal level of -26 dBm.

GB-X10 Installation Guide

2.5 Antenna Location
The optimum location for the antennas must be determined. The ideal location should provide for
ease of erecting and mounting the antenna, as well as providing unimpeded LOS to the remote
location. The following factors should be taken into account:
•Type of mounting—fixed or roof-safe pole mounting.
•Location of fiber and DC power wiring at ingress/egress of the building.
•Length of cable runs.
•Confirmed earth grounding connection points.
•Obstructions, including allowances for tree growth.
•Accessibility of the radio mounting location.
•Accessibility of the site during and after working hours.
•Monopole towers are not typically stable enough for this application and should be avoided
There is a finite incline and decline range of the elevation
adjustment when installing the radio link.
Depending upon which Manufactures Antenna is used, the mount
can only be adjusted either +/- (25, 30, or 45) degrees from the
mechanical elevation adjustment
.
2.6 GB-X10 Cover Removal
When the DC, RJ45, or SFP connections are required to be attached to the GB-X10 product, the

2.9 Cabling Considerations
2.9.1 Fiber and Power
The installation site should be inspected to determine the run paths for the fiber cable and power
cable from the radio equipment to the termination point. Locations for roof penetration should be
identified. The routing and securing of all cables should conform to all applicable codes and
requirements. Depending on the likelihood of damage due to foot traffic or equipment movement,
cabling conduit may be required. The maximum cable run length, as specified for the equipment
being installed, must not be exceeded: refer to Table 2.10-1 for cable types and limitations.
The radio requires LC type connectors on multi-mode and single-mode fibers to properly connect
between the radio and the user’s network equipment. The network equipment end of the fibers
should be terminated with connectors that match the user’s network equipment fiber interface.

Up to 10 km
9/125 μm SMF
When planning the DC power cable run from the DC power source to the radio unit, it is required to
use 12 or 14 gauge (AWG) cable to ensure adequate voltage at the radio.
12AWG wire is rated up to 9 amps while the 14AWG wire is rated
up to 6 amps which will adequately support GB-X10.
The indoor and outdoor portions of the DC power cabling must conform to all respective indoor and
outdoor national and local electrical and building codes. Requirements may differ for the indoor and
outdoor portions of the cabling, and a grounded surge protector is normally required at the point
where the cable enters the building. The DC power cabling must consist of two 12 or 14 gauge,
stranded conductors, based on your required cable run length.
The maximum cable length is dependent on the power consumption of the radio. The GB-X10 has a
DC input voltage range of ±37.5 to ±60 VDC.

2.9.2 Integral PoE
The radio can accept DC power through the Copper 5 RJ45 connector to serve as a Power over
Ethernet (PoE) interface, and / or to the 2-pin DC/power connector (which bypasses the PoE
interface).
Use an outdoor (plenum) rated (weather-protected) Cat5e cable to connect the PoE enabled source to
the Copper 5 port on the radio via the RJ45 cordgrip gland on the radio. The cord grip gland shall be
tightened to (20 +/-2in.lbs.) if a cable is routed thru the cord grip gland.
The PoE connection can also be used as a power backup for the
DC power input. In this way, if a unit’s DC power fails, the unit
will switch to the PoE power source.
A service loop shall be created on the Cat5e cable and secured to a permanent location to ensure
sufficient cable length to enable the radio to be moved during service, prevent water from following
the Cat5e cable down to the PoE, junction box, or building entrance, and to prevent compromising
the Gland connection. A suggested length is 24 inches (60 cm) from the radio to the bottom of the
service loop.
The radio is provided with a pre-installed cordgrip gland and gland plug for a water-tight seal to the
radio.
If any cables are NOT routed thru the cord grip gland, the cord grip gland shall be sealed using the
cord grip plug by firmly pushing the plug inwards while tightening to (20 +/-2in.lbs.)The following
shows the cord grip gland assembled and disassembled.

2.9.3 Conduit
Conduit is recommended for enclosure of the fiber/copper and power cables as they enter the radio.
The conduit provides a water-tight seal to the radio, as well as any weather or physical protection
required by the cables.
The conduit should be flexible, waterproof, and non-metallic. An example of this is LIQUID-
TUFF™ UL Liquid tight Flexible Non-Metallic Conduit (Type LFNC-B) or equivalent.
Conduit should be 1 inch (25.4 mm) in diameter.

GB-X10 Installation Guide
11
Installation
Conduit installation is done along with power and fiber/copper cabling installation as needed.
The radio is provided with a pre-installed liquid-tight connector for a water-tight seal to the radio.
The following shows the connector assembled and disassembled.
Once the power and fiber/copper cables are pushed thru the flexible conduit, the next step is to
prepare the grey conduit gland.
Before connecting the flexible conduit onto the grey conduit gland, unscrew the gray cap from the
gray threaded connector; remove the black rubber seal cap, yellow ferrule, and clear barrel.
Slide the gray cap and yellow ferrule over the outer jacketed flexible conduit ensuring to keep the
same orientation when removed from the radio housing. At this point, you can discard the Black
rubber seal cap.
Press the clear barbed barrel fully into the end of the inner jacketed flexible conduit.
Insert the cables ends from the flexible conduit through the grey conduit gland and route to their
appropriate locations within the radio housing.
Carefully insert the flexible conduit into the grey conduit gland on the radio housing ensuring not to
pinch any of the cables routed thru the conduit.
Carefully slide the yellow ferrule over the outer jacketed flexible conduit into the grey conduit gland
on the radio housing while firmly holding the flexible conduit against the radio housing connector
port.
Next, slide the gray connector cap onto the grey conduit gland and slowly hand tighten the gray cap
while firmly holding the flexible conduit against the radio housing connector port.

As the grey connector cap is tightened fully, the yellow ferrule
compresses against the flexible conduit outer sleeve over the clear
barbed barrel sealing the assembly for water ingress.
A service loop shall be created on the Conduit and secured to a permanent location to ensure
sufficient cable length to enable the radio to be moved during service, prevent water from following
the conduit down to the junction box or building entrance, and to prevent compromising the Gland
connection. A suggested length is 24 inches (60 cm) from the radio to the bottom of the service
loop. The opposite end of the conduit is inserted into the cable tray if on a tower or onto the NEMA
or junction box.

GB-X10 Installation Guide
13
The first tie provides the first anchor and strain relief. Gentle curves provide the necessary radius for
the fiber to minimize signal loss and eliminate sharp angles lessening voltage potential from being
induced during lightning storms.
With a short conduit, the radio's opening has been moved further away and moisture is unable to
migrate into the radio.
Tower Installation
Secure the conduit with suitable braces to ensure long-term performance. The total length of the
conduit should be a minimum of 10 feet (3 meters), but the length required to reach the cable tray is
site-specific.
Once the cables are installed, seal the conduit opening for additional protection from insects using
amalgamated tape or sealant.
All cables used should be outdoor-rated.
Below the conduit, secure the cables approximately every 1.6 feet (1/2 meter) onto the tower's cable
tray. Running the cables to the cable tray is recommended to provide additional environmental
protection.
Roof-Top Installation
Secure the conduit with suitable braces to ensure long-term performance. Terminate the network end
of the conduit into a NEMA enclosure or junction box. Terminate the conduit at the NEMA
enclosure by either:
•Drilling a hole in the bottom of the NEMA box for the fitting; or
•Removing one of the built-in conduit punch-outs if provided on the NEMA box.
Use amalgamated tape or sealant to create a watertight seal at that junction.

2.10 Power Supply Connection
The GB-X10 radio power input connector is powered off the end customer-supplied “+” or “-
”48VDC power source.
The end customer shall ensure they have a method of disabling the
DC Power to the Radio prior to connecting or disconnecting any
Voltage lines to the Radio.
On the radio end, no connectors are required; just strip the insulation off the DC power wires ends
and press the DC power wires into the connector while observing the correct polarity. Once pressed
in, the wires are locked in place.
As an alternative to the 2-pin DC/power connector, use the Copper 5 RJ45 connector for PoE.
Connect the PoE enabled source to the Copper 5 port with an outdoor-rated Cat5e cable. This can
also be used to back up the 48VDC power if a unit’s DC power fails. The 48VDC power acts as the
primary source, and if a power failure occurs, the unit switches to the PoE power source.
The DC power input will always override the Power Source
Equipment (PSE) for the PoE. If the DC power input fails, the
PSE/PoE detects the power loss and activates the PSE to power
the system. Both sources must be connected for this operation to
work as described.
To remove the DC
power wires, simply
press a flat blade
screw driver into the
slots on the
connector and pull
the wires out to
remove.

2.11 Grounding & Lightning
Proper grounding of the outdoor equipment reduces
electromagnetic interference, provides lightning protection, and
protects against electrical discharge.
Using improper techniques in lightning-prone geographic areas
may pose a danger to local personnel.
The source and connection points for the building-to-earth
ground in the vicinity of the antenna location should be
determined.
Customers can add addition surge protection to the DC electrical cables by adding a surge
suppressor. The surge suppressor should be installed before entry point where the DC electrical
cables exit/enter the building. Please review your local electrical codes.
Solectek does not supply external surge suppressors. However, a suggested surge suppressor is the
Smith Power’s Transtector DC Surge Protector, part number 1101-1110, shown below. Pole-Mount
Bracket: 1000-1164 sold separately.
2.12 Environmental
The structure to which the equipment will be mounted should be adequate to bear all wind and
weather conditions. The environmental conditions at the location must conform to the operating
environment specified for the equipment.
