1.7 Lightning Protection
WARNING: The following notes are general recommendations for the system.
The wireless equipment should be installed by a qualified professional installer
and must follow local and national codes for electrical grounding and safety.
Failure to meet safety requirements and/or use of non-standard practices and
procedures could result in personal injury and damage to equipment. A direct
lightning strike may cause serious damage even if these guidelines are followed.
All outdoor wireless equipment is susceptible to lightning damage from a direct hit
or induced current from a near strike. Lightning protection and grounding practices
in local and national electrical codes serve to minimize equipment damage, service
outages, and serious injury. Reasons for lightning damage are summarized as:
- Poorly grounded tower/antenna sites that can conduct high lightning strike
energy into equipment.
- Lack of properly installed lightning protection equipment that can cause
equipment failures from lightning induced currents.
A lighting protection system provides a means by which the energy may enter
earth without passing through and damaging parts of a structure. A lightning
protection system does not prevent lightning from striking; it provides a means for
controlling it and preventing damage by providing a low resistance path for the
discharge of energy to travel safely to ground. Improperly grounded connections
are also a source of noise that can cause sensitive equipment to malfunction.
A good tower grounding system disperses most of the surge energy from a tower
strike away from the building and equipment. The remaining energy on the IF
cable shield and center conductor can be directed safely to ground by using a
lightning arrestor in series with the IF cable.
To limit the equipment damage due to a lightning strike, the following practices
are recommended for the wireless system:
- Provide direct grounding from the antenna mounting bracket, the radio and
antenna and the lightning arrestors to the same ground point at the base of the
tower or a ground bus on the building. Use the grounding screws on the antenna
bracket and the radio and antenna for terminating the ground wires.
- Install one RF lightning protector between the radio and antenna in series with
the RF cable.
- A lightning arrestor in series with the IF cable at the point of entry to the
building.
- Install a lightning arrestor in series with the IF cable at the transceiver on the
tower/mast.
- The AC wall outlet ground for the terminal must be connected to the same
grounding system as the radio and antenna lightning protectors.
- The ground connection on the back of the terminal should be connected to the
same ground for the building.

2.1 Site Survey
The RF signal path profile is required to determine the location, height, and aiming
requirements for installation of the wireless system radio/antenna.
2.1.1 Site Path Survey
Before the installation of the equipment, a site survey should be completed. Copies
of this survey data must be provided to the installation team. This data should
include the following:
1. Copies of the path profile so that the installation height requirements of ODU
can be determined. The path profile should show the clearance above natural
and man-made objects by at least 60% of the First Fresnel zone. This will
provide a clear line-of-sight (LOS) path.
Figure 1: Fresnel Zone Radius
2. The Redline system is very robust and will work without performance
degradation in an optical line-of-sight (OLOS) path where a straight path is
clear between the two end points but the 60% of the First Fresnel zone is not
clear. If the straight path is blocked, the non-line-of-sight (NLOS) path can still
operate using reflections and diffraction.
Figure 2: Fresnel Zone Obstruction
A critical parameter to consider is the range at which communicating wireless
systems are required to operate. Range performance is determined by empirical
formulas that consider a number of equipment and environmental factors.

BFW Installation Guide
AN-30e & AN-50e Systems
The Link Budget Tool developed by Redline will calculate expected performance
of the link for a specified range. Ensure that the installation sites will meet
performance requirements before moving to the next step.
The completed path profile should include the following information:
Table 1: Site Path Profile
Antenna Description
Location Instructions to identify the location for installing the antenna mast.
May include blueprints and specify material list.
Height Mounting height for antenna.
Azimuth Horizontal aiming direction for the antenna (magnetic or GPS
compass)
Elevation angle Vertical aiming for antenna (spirit level).
Expected RSSI Use the Link Budget tool to determine the expected receive signal
strength (RSSI).

2.1.2 Identify Best Path
The next step is to conduct a general site survey to determine the location for the
antenna. This involves a survey to identify building and structures that can be used
to mount an antenna. Refer to the specification for the maximum IF cable length.
For maximum performance in OLOS deployment, it is recommended to mount the
antenna in a location where there is direct line of sight to the receiving wireless
system. If the obstruction in the path is not exceptionally high, it may be possible
to aim both antennas near the top of the obstruction. The antenna should be
positioned to provide maximum clearance within the first Fresnel zone of the
direct path (as high as possible, on either a tall building or tower).
The wireless system also supports installation in non-line-of-sight (NLOS)
conditions. A satisfactory multipath RF signal can often be obtained by directing
each antenna towards a structure in sight of both communicating wireless systems.
Figure 4: Antenna Mounting Locations
The recommended method for obtaining a satisfactory RF signal is to test a
number of antenna positions and measure the signal-to-noise ratio and received
signal strength (RSSI) for each position.
It is also important to test for RF interference at the intended rooftop or tower
installation site. RF interference can be caused by any wireless system in the area
that is operating in the same frequency band as the wireless. Accurate analysis
requires the use of specialized RF test equipment. The primary purpose of these
tests is to determine what channels are available for use on the wireless system.
2.1.3 Antenna Mounting and IF Cable Routing
When the antenna location has been established, plans should be made for
installation of the antenna mast or alternative mounting equipment. Plans should
be made for routing the IF cable from the radio/antenna to the terminal. In some
locations it may also be possible to install the IF cable on the outside of the
building. If the building must be penetrated to run the IF cable, it is important to
verify that building blueprints and/or drawings are up to date and accurate, and
that all permissions are obtained for the required modifications.

2.2 Antenna Alignment
Obtain accurate antenna pointing azimuth and elevation angles for each
installation site. This will allow approximate alignment of the two antennas by
using GPS or magnetic compasses.
2.3 Unpacking the AN-30e/AN-50e System
The system comes packaged with the following items:
- Indoor terminal and mounting brackets
- T-54 or T-58 transceiver
- Antenna and mounting bracket
- RF and IF cables
- AC and/or DC power cables
- Optional items (such as lightning protectors)
- Documentation CD-ROM
A complete list of items included in the system is available on the packing list
included with the system.
2.4 Adaptive Modulation
AN-30e System
It is recommended to initially install and test the AN-30e as a data-only system (no
TDM traffic) with adaptive modulation enabled. This setting will allow for easier
antenna setup and alignment as the wireless equipment can establish a connection
using any available modulation and coding scheme.
When the system is completely installed and operating at the required stability and
throughput, adaptive modulation should be disabled before running live TDM
traffic over the wireless. With adaptive modulation enabled, temporary
interference could cause the AN-30e system to switch to a modulation/coding
scheme that does not support the required throughput level for the TDM traffic.
AN-50e System
It is recommended to initially install and test the AN-50e with adaptive modulation
enabled. This setting will allow for easier antenna setup and alignment as the
wireless equipment can establish a connection using any available modulation and
coding scheme.

mast diameters from 1 ¾" (4.45 cm) to 4 ½" (11.45 cm). This mounting
bracket can be used for either the 1 foot (305 mm) and 2 foot (600 mm) flat-
panel antennas.
2. Complete the assembly of the mounting bracket. Ensure that you utilize all
washers and split washers supplied. The antenna N-connector should be
located to the right and just above the mounting bracket to allow ease of access
when weatherproofing the connectors.
Figure 5: Antenna Bracket Assembly (with transceiver)
3. Mount the ODU and the antenna securely to the mounting bracket. Ensure both
antennas have the same polarization. The arrows located at the rear of the
antenna indicate the polarization as shown in Figure 6. The vertical arrow
pointing UP indicates vertical polarization.

3.2 Weatherproofing
3.2.1 Weatherproofing Materials
THE IMPORTANCE OF PROPER WEATHERPROOFING CANNOT BE
OVERSTRESSED!
Do not use PVC tape. We recommend sealing tapes designed for outdoor use:
- Scotch 2200 series of Vinyl Mastic rolls
- Scotch 130C Linerless Rubber Splicing Tape.
- 3M Scotch Super 88 Electrical Tape
These are heavy-duty weather, abrasion, and UV resistant and can be purchased at
most hardware stores.
Use rubber mastic putty or duct sealing putty must also be used to complete the
weatherproofing. The professional installer may use his own weatherproofing
preferences, provided they do not use silicon-based materials. Redline does not
70-00042-01-02 Proprietary Redline Communications © 2005 August 2005
Page 15 of 34

BFW Installation Guide
AN-30e & AN-50e Systems
recommend silicon seal or glue. Silicon is difficult to apply accurately, can leave
gaps, and is difficult to remove.
3.2.2 Applying the Weatherproofing
This section provides a pictorial primer on correct weatherproofing procedures.
1. Check that all connectors are correctly tightened.
Figure 8: Weatherproofing Procedures - Part 1
2. Begin to wrap the splicing tape. Start as close to the radio/equipment body as
possible. Stretch and wind the tape back along the connector housing making
very sure there are no gaps in the tape.
Figure 9: Weatherproofing Procedures - Part 2
70-00042-01-02 Proprietary Redline Communications © 2005 August 2005

BFW Installation Guide
AN-30e & AN-50e Systems
3. Continue to wrap the tape tightly along the cable.
Figure 10: Weatherproofing Procedures - Part 3
4. Work the mastic putty well into the area between the connector and the body
of the radio.
Figure 11: Weatherproofing Procedures - Part 4
5. Continue to work the putty in making a watertight seal. The connection is now
well weatherproofed. This method of weatherproofing must be completed on
ALL external connections. If lightning arrestors are used, all the associated
connections and arrestors must be wrapped completely in splicing tape.

3.3 IF Cabling
The IF cable connecting the IDU to the ODU is one of the most important
components in the installation process. The cable quality and loss profile has a
critical bearing on the performance of the wireless link. If the customer selects to
purchase the cable separately, the cable must be of a recommended type and be
assembled using the recommended connectors. See the following sections for
approved cables and connectors.
3.3.1 IF Cable Routing
Before routing the IF cable, check the following:
- Check drilling requirements, through a wall or ceiling for routing the cable.
- Look for a building plan for any existing cable routing.
- Avoid excessive force or stress on the connectors that may damage the cable.
The minimum bend radius is 1" (2.5 cm) for RG-6 and 4" (10 cm) for RG-11.
- Secure the cable along its complete indoor and outdoor length with tie-wraps.
- Do not use connectors as cable-grips to pull cable through raceway or conduit.
3.3.2 IF Cable Selection
The IF cable carries the following signals between the IDU and ODU:
- OFDM IF signal at 815 MHz
- Local Oscillator (LO) signal at 2.5 GHz
- 24 Volt DC voltage for the T-58/T54 Electronics
- Control signal between IDU and ODU
F-type connectors are used for the IF cables. Crimpable F-connectors using the
center conductor of the cable as the connector pin must not be used for the RG-11
cable. The diameter of the RG-11 cable center conductor is >1 mm, and will
damage the mating F-connector on the ODU/IDU if used as the connector pin. In
addition, the RG-6 and RG-11 connector pin must not be longer than 0.13" (1 cm).
If incorrect F-connectors are used the ODU/IDU is not covered under warranty. To
avoid damage, use only Redline approved F-connectors for RG-6 or RG-11 cable.
Refer to the following list of recommend IF cables and manufacturers.
