A Yaggi or panel antenna (it depends on the booster model and its power), as donor/outdoor antenna, is installed at the top of the roof to pick up good mobile signals from the base station, and sends them through the cable to the booster where the signals get amplified significantly;...

Page 8: Outdoor Antenna Installation
ANTENNAS AND CABLES SETTING UP Outdoor antenna installation The repeater’s main function is to improve weak RF signals in an area. The formula is: Input power + Gain= Output power. The signal strength from an outdoor antenna directly affects the efficiency of the indoor coverage. It is very important to choose the correct outdoor antenna location in order to get the best signal. - Page 9 Installation of a panel antenna as an outdoor antenna Installation of Yagi wide band antenna as an outdoor antenna Installation of a Yaggi antenna as an outdoor antenna Cable layout and connector assembly 1. Keep the type, specifications, routing direction, location and curvature radius of cables in compliance with the model requirements.
- Page 10 Lightning Surge Protector Setup Please read carefully the instructions provided with the coaxial surge protector to ensure safe and effective installation in terms of grounding and maintenance. 1. Connect the male N-connector of the surge protector to the female N-connector of the outdoor antenna. 2.

Page 11: Indoor Antenna Installation
Indoor antenna installation Correct antennas types shall be used according to the site conditions and the requirement. 1. Omni antenna (ceiling Omni or whip antenna) shall be installed in the center and radiate all directions. 2. It is better to use a directional panel antenna or Yaggi antenna when the area shape is long and narrow (corridors, long row of houses in two sides, tunnels or elevators or rural open space). -
Page 12: Repeater Installation
REPEATER INSTALLATION Installation requirements Installation Location Requirements 1. The repeater shall be installed indoor in a cool, dry and ventilated room without erosive gas or smoke, or on a cool and ventilated wall to ensure excellent heat dissipation. 2. Installation height should be sufficient for RF cable wiring, heat dissipation and maintenance. 3. - Page 13 Installation with 2 indoor antennas INSTALLATION STEPS 1. Find an appropriate position for an outdoor antenna. ( see the r equirements in 6.1. sect. ) 2. Plug in the outdoor antenna to the mobile booster from BS side and fasten tightly. 3.

5. Don’t put the antennas (outdoor and indoor) too close to each other. Recommended distance is 10-20 m. Be sure to point them to the opposite directions to avoid the risks of malfunctions such as self-oscillation or interference. It's also recommended that they are not placed in direct vision to each other (use metallic obstacles, wall, ceiling, slab, etc). -

Repeater Settings Indicator Light Instructions Introduction screen. The introductory page is displayed at the screen for 10 sec during the system check-up. When the device completes the internal self test, it shows the standby screen. If the arrow down is displayed at the bottom right corner, the device has detected signal reception problems. -

LINE 2. MS shows the output power of a booster. Note! The MS (output power) index must be between +01 and +15 dBm. LINE 3. Device gain shows the current gain (left) and maximal gain (right) of the device. For optimal function both values must be equal (current gain=max gain). - Page 17 If the device detects that the outdoor antenna is too close to the indoor, change the position of either or both antennas to avoid self-oscillation. Mount them at least 15m one from another. If the device detects self-oscillation between the antennas and says that the system is being adjusted, it means that the system has detected the problem of bad isolation between the antennas and AGC is adjusting the system gain automatically to make the device work correctly.
- Page 18 In case of installation errors an exclamation point/arrow appears on the LCD screen. It happens in two cases: 1. Input signals (external BS) are weak. It can happen that even with a weak signal the amplifier works well. In this case, nothing should be done. Just ignore a flashing exclamation point.
- Page 19 antenna or its installation position or replace it for an antenna with higher gain. - Check whether it is necessary to use additional indoor antennas as barriers block signal penetration; also check whether the repeater’s power is enough; please install extra indoor antennas or replace the repeater for another model with higher power level.

- Page 21 1. Will booster increase the RF radiation? No, it will decrease instead. Every cell phone irradiates heavily being in zones with poor mobile signal as a cell phone is constantly in searching mode. The danger is your cell phone is about 2cm to your body, which makes its usage rather harmful. And when a booster is installed, it improves the mobile signals in the coverage, and your cell phone stops irradiating strongly, thus it will reduce the RF radiation of the mobile phone tremendously.
