WARNING! Installation of antennas near power lines is dangerous. For your
safety, follow all installation directions and keep safe distance from any
high voltage power lines that could result in shock or loss of life.
WARNING! This equipment complies with FCC & IC radiation exposure
limits set forth for an uncontrolled environment. This transmitter must not
be co-located or operating in conjunction with any other antenna or
transmitter. The signal booster with server antenna must be installed to
provide minimum 20 cm separation distance between the server antenna to
the body of user or near by person. The donor antenna used for this
transmitter must be fixed-mounted on outdoor permanent structures with a
separation distance of at least 1.5 meters from all persons during normal
operation.
Additional wiring required to install the HB-20 system should comply with national
or local governing Electrical Codes. Indoor RF coaxial cable installations should
comply with local Electrical Code requirements.
The HB-20 booster is designed for indoor application. The housing is not
waterproof, so please keep it away from water, rain and any chemical liquid.
Do discharge the static before you touch the connectors of the booster.
Do not open the module inside the booster unless you are authorized.
The power supply unit in the HB-20 booster is supplied from the mains (primary
AC power) that contains dangerous voltage level which will cause electric shock,
Please turn off the mains before you install / uninstall the booster.The primary AC
power should be in the range of AC100-240V, 50/60Hz. Booster will be damaged
if the primary AC power is out of the range.
The RF electric performance of the HB-20 booster conforms to ETSI
requirement of the inter modulation and spurious emission. It avoids the
interference problem.

SECTION 2
2.1 Introduction: Booster Theory / Background
In mobile cellular communication system, boosters provide the radio frequency
(RF) coverage to areas, which either lack signal, or the required signal strength is
inadequate for mobile phone performance. To the typical user, this translates to
the inability to place or receive mobile phone calls in or out of the area, and in
most cases will result in a dropped call while entering into the poor coverage
area. Insufficient wireless coverage can occur both indoors and outdoors, and
may include indoor areas such as office buildings, parking garages, apartment
buildings, shopping malls, and residential homes. Outdoor areas are degraded by
geographic topologies such as mountains, valleys, dense foliage and high rising
urban landscapes which can easily degrade or obstruct the cell site’s signal from
the mobile phone.
The weak coverage problem can be solved by installing an active booster
system, designed for use in a multitude of installation configurations. Booster
systems provide an effective solution by redirecting, filtering and amplifying the
available signal at the donor antenna, into the weak coverage area, through a
properly selected interior coverage antenna. The illumination of the weak
coverage area allows the user’s handset to operate as intended within the
building or weak coverage area, while maintaining the user’s call clarity .

SECTION 3
3.1 Description of HB-20 Booster installation Kit
The HB-20 booster system contains an automatic power control, bi-directional
amplifier (BDA) supplied along with a donor antenna (highly directive outdoor
antenna) and server antenna (indoor omni directional antenna), specifically
designed for interior configurations. The donor antenna must be pointed toward
the cell of the base station from where the signal is to be picked up and is usually
mounted on the exterior of the building so as to receive the maximum forward
signal level from the base station. The indoor antenna of HB-20 booster provides
RF signal in all directions downward and outward from the installation point.. A
adopter is supplied with HB-20, powered by universal 100-240 VAC mains
supply. A standard length of 10 mtr RF coaxial cable with connectors is supplied
to connect the donor antenna and HB-20 booster. Any other RF coaxial cable
length is also available optionally, on request.
