Page 6: Repeater System Overview
5. 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;... - Page 7 Optionally: Splitters or couplers: when the building structure is too complicated or there is big loss due to thick walls or other reasons, splitters or couplers shall be used so that more antennas can be installed in separate zones to distribute the signals to each corner of the coverage area.

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. It is very important to choose the correct outdoor antenna location in order to get the best signal. -

Installation of a Yaggi antenna as an outdoor antenna 6.2. Cable layout and connector assembly 1. Keep the type, specifications, routing direction, location and curvature radius of cables in compliance with the model requirements. Place cables in correct order, bend them smoothly, and protect the surface from any damage. 2. - Page 10 Requirements to indoor antenna installation: indoor antenna should be 5 meter distance from an outdoor antenna indoor antenna should be at least 2 meters above the ground indoor antenna should be fixed vertically with the ground.

The equipment works correctly when power LED indicator light P is on, any other status means power failure or equipment failure. The equipment works correctly when both Up-link indicator light U and down-link indicator light D are on. The up-link incoming signal is very strong and the equipment output is large when the light U is flashing slowly. - Page 14 Remark: Reduce attenuation values * — by ensuring the isolation level Increase output power * — recommended ways: to adjust outdoor antenna direction/location, or replace it to an antenna with higher gain to increase input signal strength. 7.4.2. Repeater can not communicate in Power-ON status 1.

- Page 16 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. 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.
