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 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.

ground wire isn’t looped or coiled. The suitable grounding locations can as follows: a ground rod (a metal rod normally buried outside the house), an electrical service panel (it is connected to the ground rod of the house), metal structure of a building (provided that this structure is grounded itself). - Page 11 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). Requirements to indoor antenna installation: •...

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 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. Plug in the indoor antenna to the mobile booster from MS side and fasten tightly. 4.

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. Accessories selection Choosing accessories pay attention to the two characteristics – frequency and impedance. All accessories shall support the repeater’s frequencies. - Page 15 Three band repeater display and operation interface 1. The1 line shows the working status of Band 1 – EGSM 900 MHz. 2. The 2 line shows the working status of Band 2 – WCDMA 2100MHz . 3. 5 bars appearing next to the output signal strength indicator signify the maximum output power of the repeater. One signal bar is 5 dB.
- Page 16 When the “Smart” function is enabled, the repeater sets up the suitable gain automatically thus not causing any interference to the mobile network. The repeater also has Manual Gain Control (MGC) feature that enables users/ engineers to reduce the gain of the repeater manually with the help of a touch screen, if any oscillation is detected.

The repeater also has a Network Safe / MUTE feature that automatically shuts off the repeater in order not to interfere with the operators’ cellular network. Users shall make sure that the LED indicators remain green at all times for optimum system performance. - Page 18 - Check if it is necessary to adjust the direction of the indoor antenna. - Check whether it is necessary to add one or more antennas to enhance the coverage in special areas. Remark: • Reduce attenuation values * — by ensuring the isolation level •...
- Page 19 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 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.
