REPEATER SYSTEM OVERVIEW The picture below shows how simple and fast booster installation is and how effectively it works. 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;...

6. ANTENNAS AND CABLES SETTING UP 6.1. 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. -

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 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).

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. - Page 12 INSTALLATION STEPS 1. Find an appropriate position for an outdoor antenna. ( see the requirements in 6.1. sect. ) 2. Plug in the outdoor antenna to the mobile booster from BS side and fasten tightly. 3. Plug in the indoor antenna to the mobile booster from MS side and fasten tightly. 4.

7.2.2 Repeater’s ports description 1. Outdoor port: connected with the outdoor antenna by cable 2. Indoor port: connected with indoor antenna directly or by cable 3. DC IN: connected with power supply. 7.2.3 Accessories selection Choosing accessories pay attention to the two characteristics – frequency and impedance. All accessories shall support the repeater’s frequencies. -

BS - Outdoor port for connecting an external antenna. MS1 and MS2 - Indoor ports for connecting two internal antennas. DC 6-12V: for connecting a power supply. Note: You can use only 1 indoor antenna instead of 2 in case the area to cover is small (if distance between two antennas is less than 3m). - Page 15 2. After the device finishes starting up, the main screen with signal readings will be displayed. G9 – 900 MHz signal D18 – 1800 MHz signal W21 – 2100 MHz signal I - Input signal that the device receives from outdoors. This value is always measured as negative with the sign “-”...
- Page 16 Max Gain – The booster’s highest gain that is set by the factory. Working Gain – The current gain measured while the booster is working under different conditions. When the Input signal is weak, the booster will work with at the max gain, but when the device detects too much strong input signal, it will automatically reduce the gain to avoid self-oscillation of the system.

The device detected that the external antenna is too close to the internal antennas. The booster will shut down automatically to protect the system from damage. It will restart after the problem is resolved. Solution: Ensure good antenna isolation. • Keep minimal distance (10 - 20m) between the outdoor and indoor antennas. The stronger input signal, the larger distance between antennas should be. - Page 18 Mode on your cell phone, use bars on the screen of your mobile phone to evaluate the change. If the signals in most areas have not been improved, please check recommendations below again: - Weak input signal leads to low output power. To increase input signal power level, change the direction of the outdoor antenna or its installation position or replace it for an antenna with higher gain.
- Page 19 7.4.2 Repeater can not communicate in Power-ON status 1. The power is on but there is a signal fluctuation or a flash signal. The phone call cannot be made/ received. It shall be caused by the insufficient isolation between outdoor and indoor antennas. Please take the following measures: - Firstly check whether the alarm LED lights.
- Page 20 8. FAQ 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.
