Antenna Installation
Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used
for this transmitter must be mounted on permanent structures.
The FCC regulation mandate that the ERP of type A signal boosters should not exceed 5W, this is
equivalent to 8.2W EIRP.
Therefore the max antenna gain allowed for this type of signal booster should be limited to the values
given by equation (1) for the service antenna and equation (2) for the donor antenna
Equation (1) - Max SERVICE antenna gain
Max SERVICE antenna gain (dBi) = 39.1 – (37dBm - # of antennas in dB – cable losses in dB).
For example:
No. of Antennas
Cable Losses
Max Allowed Antenna Gain

39.1 - (37-6-3) =11.1dBi

3
39.1- (37-0-3) = 5.1dbi

3
39.1- (37-10-3) = 15.1dbi
Equation (2) - Max DONOR antenna gain
Max DONOR antenna gain (dBi) = 39.1 – (37dBm - cable losses in dB).
For example:
No. of Antennas
Cable Losses
Max Allowed Antenna Gain
1
10
39.1 - (37-10) = 12.1dBi
Compliance with FCC deployment rule regarding the radiation of noise
Good engineering practice must be used in regard to the signal booster’s noise radiation. Thus, the
gain of the signal booster should be set so that the ERP of the output noise from the signal booster
should not exceed the level of -43 dBm in 10 kHz measurement bandwidth.
In the event that the noise level measured exceeds the aforementioned value, the signal booster gain
should be decreased accordingly.
In general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band should not
exceed -70 dBm in a 10 kHz measurement bandwidth.
The 3604 BSF0038 Series Repeater has a noise level of -45 dBm in 10 kHz measurement at 1 MHz
spectrum outside the passband of the signal booster and an in-band noise level at around -45 dBm in
a 10 kHz bandwidth. Therefore, the noise at the antenna input port should be calculated based on
equation (3).

AXELL BSF-4004 BSF0038 SERIES REPEATER
PRODUCT DESCRIPTION AND USER’S MANUAL
Equation (3) - Input Noise to service antenna
Input Noise to service antenna:
-45 dBm + Service Antenna gain – Antenna splitter losses in dB – cable loss in dB
Example:
Signal booster connected to 20 service antennas with a 100m long ½ inch cable.
Losses of such a cable with the connectors = ~ 12dB
Gain = ~ 2 dBi
Assuming 20 service antennas: antenna splitter losses = 15 dB
Based on equation (3) Input antenna noise (to the antenna) = -45+2-12 -15=-70 dBm
The inband input noise to the antenna should be -45+2 -12-15= -70dbm
NOTE: In this example there is no need to add an external band pass filter to attenuate the out of
band noise. If fewer antennas are deployed then additional filtering may be required
Conclusion:
Good engineering practice requires that in general when the out of band noise measured at the
service antenna input is more than -70 dBm per 10 kHz measurement bandwidth, an external band
pass filter should be added to attenuate the out of band noise level.
All Axell Wireless repeaters include high selectivity duplexers and filters to attenuate the out of band
noise. Should additional filtering be required, we have a comprehensive range of interference filters
which can be supplied upon request.

General Safety Warnings Concerning Use of This System
Always observe standard safety precautions during installation, operation and maintenance of this
product.
Caution labels!
Throughout this manual, there are "Caution" warnings. "Caution" calls
attention to a procedure o
r practice, which, if ignored, may result in
injury or damage to the system, system component or even the user.
Do not perform any procedure preceded by a "Caution" until the
described conditions are fully understood and met.
Danger: Electrical
Shock
To prevent electrical shock when installing or modifying the system
power wiring, disconnect the wiring at the power source before
working with un insulated wires or terminals.
Caution: Safety to
personnel
Before installing or replacing any of the equipment, the entire manual
should be read and understood.
The user needs to supply the appropriate AC or DC power to the
repeater. Incorrect power settings can damage the repeater and may
cause injury to the user.
Please be aware that the equipment may,
during certain conditions
become very warm and can cause minor injuries if handled without any
protection, such as gloves.
Caution: RF Exposure
RF radiation, arising from transmitter outputs connected to AWL’s
equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or
because a ‘spare’ output has been left un-
terminated. Either of these
conditions would impair the system’s efficiency. No investigation
should be carried out until all RF power
sources have been removed.
This would always be a wise precaution, despite the severe mismatch
between the impedance of an N type connector at 50Ω, and that of free
space at 377Ω, which would severely compromise the efficient
radiation of RF power. Radio
frequency burns could also be a hazard,
if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both
local & statutory) regarding exposure of personnel to RF radiation.
When connect
ed to an antenna, the unit is capable of producing RF
field strengths, which may exceed guideline safe values especially if
used with antennas having appreciable gain. In this regard the use of
directional antennas with backscreens and a strict site rule that
personnel must remain behind the screen while the RF power is on, is
strongly recommended.
Where the equipment is used near power lines or in association with
temporary masts not having lightning protection, the use of a safety
earth connected to the case-earthing bolt is strongly advised.

Exercise caution as follows:
•Do not stare into beam or view with optical instruments. Optical
transmitters in the fibre optic converter can send out high energy
invisible laser radiation. There is a risk for permanent damage to
the eye.
•Always use protective cover on all cables and connectors which
are not connected.
•Never look directly into a fibre cable or a connector.
•Consider that a fibre can carry transmission in both directions.
•During handling of laser cables or connections, ensure that the
source is switched off.
•Regard all open connectors with respect and direct them in a safe
direction and never towards a reflecting surface. Reflected laser
radiation should be regarded as equally hazardous as direct
radiation.

PRODUCT DESCRIPTION AND USER’S MANUAL
1 Introduction
The BSF 4004 is a fibre optic fed UHF repeater. It is part of a system that is fed from an Optical
Master Unit (OMU), supporting WDM technology, lowering the number of fibres needed per system.
The maximum optical loss of up to 10dB is allowed over the fibre interconnecting the OMU II and
the most distant last remote unit that the OMU supports. This offers great flexibility when providing
RF coverage in areas where it is not possible to rely on off-air transmission.
The fibre optic system is easily remotely monitored and controlled by Axell Wireless effective
supervision tool, Axell Wireless Element Manager.
The BSF-4004 includes automatic optical gain settings, where the gain is adjusted in the downlink
chain by measuring the level of the pilot carrier sent from the Optical Master Unit (OMU). The level
of the received pilot carrier is continuously monitored.

PRODUCT DESCRIPTION AND USER’S MANUAL
1.2 ALC
The repeater is equipped with an ALC, Automatic Level Control. The ALC feature enables
maintaining the maximum defined output level.
The repeater has a defined maximum output level. If the input signal amplified by the gain set
exceeds the set output limit, an ALC (Automatic Level Control) loop is activated. This ALC ensures
that the amplifier does not add distortion to the radio signal. Below are examples of the ALC function
for one and two carriers.
1.3 Operating Temperature
The BSF-4004 is designed primarily for multi carrier purposes. If the repeater is run at full output
power over a long period of time, the convection cooling may not be enough. The repeater is
equipped with a power management function that steps down the power and, if needed, fully shuts
down the amplifier chains until temperature reaches normal values. In situations where a repeater will
be run in such a manner extra cooling can be provided by putting the repeater in a temperature
controlled environment or via external fans.

2.2.2.3 Installation Criteria
Determine the antenna installation configuration, according to the transmission
requirements and the installation site conditions.
Installation requirements:
•An indoor antenna should be installed at a convenient location. It should be free of metallic
obstruction.
Install the Service Antenna at the designated height and tune it roughly toward the Service coverage
area.
2.2.3 Service (Mobile) Antenna Installation Criteria
Determine the antenna installation configuration, according to the transmission requirements and the
installation site conditions.
Installation requirements:
•An indoor antenna should be installed at a convenient location. It should be free of metallic
obstruction.
•Install the Service Antenna at the designated height and tune it roughly toward the Service
coverage area.
•Installation of this antenna must provide a minimum separation distance of 49 cm from any
personnel within the area.
2.3 RF Cabling Requirements
•For all coaxial connections to/from the Repeater - high performance, flexible, low loss 50Ω
coaxial communications cable.
•All cables shall be weather-resistant type.
•Cable length - determined by the Repeater installation plan. When calculating the cable length,
take into account excess cable slack so as not to limit the insertion paths.
•Make sure that cable and connector are compatible. Using cables and connectors from the same
manufacturer is helpful.
•All connectors must be clean and dry
•Waterproof all outdoor connections using silicone, vulcanizable tape or other suitable substance
as moisture and dust can impair RF characteristics.
•Make sure enough room has been allocated for the bending radius of the cable. RF cables must
not be kinked, cut or damaged in any way
•Connect the RF cable to the antenna tightly but without damaging threads
•Fasten cables tight to cable ladder or aluminum sheet
•For short length of feeder cables use ½ “, for longer feeder cables use 7/8”. Chose thicker coax
cables for lower attenuation. Minimize the length of the coax cables to reduce the attenuation
•Use jumper cable for easy installation. The RF Coaxial cable can be substituted at each end with
a jumper cable.
