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 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.

Status ALARM It is working in linearity Green Warning: Input signals may be not enough, so please check on coverage effect, do not do anything if it is good coverage; otherwise please adjust the repeater system to get better coverage. A little bit stronger input signals or slight self oscillation have occurred. - Page 16 DIP switch uplink attenuation setting: 0 dB 5 dB 10 dB 15dB For single system plastic closet?

Repeater Commissioning Downlink gain setting First the alarm LED only indicates the downlink input power level, here we use color of Alarm LED to adjust the gain of the repeater. Alarm LED color must remain green. As for the downlink working performance, it is a good working point that Alarm LED maintains “Green”... -
Page 19: System Test
System Test Check whether the coverage is good 1. Take a test with a mobile phone or a data card (engineering mobile phone is preferred). To test signal level with a cell phone, make use of its engineering mode (Field Test Mode), which is an application available in free access or a phone mode requiring no extra setups. - Page 20 For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. The closer dB signal level to 0, the better cell phone reception you’ll get. • -105 to -100 = Bad/drop call •...
- Page 21 - Use some obstacles (Such as walls). 2. The repeater’s power is on but the phone cannot get connected to the network and still can not communicate. Reason 1: There are loose or wrong connections in the repeater system. Solution: Please try to fasten the connections between different parts of the system. Reason 2: The signals received by outdoor antenna of other operators nearby are too strong.
- Page 22 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.
