SZZJ-A10~17LF-LCPA User Manual 4. Block diagram and work principle 10dBm, 13dBm, 17dBm repeater is basically a bi-directional amplifier, the downlink signals are received by the repeater from cell tower by the donor antenna, filtered by its internal duplexers and FC unit, amplified by low noise amplifier (LNA) and downlink PA unit, and then sent via the server antenna to the area to improve mobile signals for mobile phones.
SZZJ-A10~17LF-LCPA User Manual 5. Recommended booster antenna kitting 5.1. Recommended donor/outdoor antenna Function: Pick up donor signals from the cell tower and send to the repeater by cable; the power level and quality of the received signals influence a lot on the coverage effect. Donor antenna also transmits the uplink signals from the repeater to cell tower. Log Periodic Antenna This is a wideband directional antenna with high gain.
SZZJ-A10~17LF-LCPA User Manual The outdoor panel Antenna The outdoor panel antenna is also a directional antenna with 120 degree coverage. It’s the wide range type that could pick up the signal from multi carriers. This antenna should be installed in a vertical position and face to the BTS tower for better reception. 5.2.

It’s usually directly connect to the booster, and then put the repeater in the central of the covering area for signal distribution. 5.3. Optional booster kitting for fixed installation 5.3.1. The outdoor booster antenna kitting. There are many different options with different type of antennas or variable cable length.
SZZJ-A10~17LF-LCPA User Manual walls, etc., splitters or couplers shall be used so that more antennas can be installed in more areas to distribute the signals to each corner of the coverage area. 6.

Installation of donor antenna The repeater’s main function is to improve weak RF signals of an area. A simple formula: Input power+ Gain= Output power. The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage. It is very important to choose the donor antenna location in order to get the best signals.
SZZJ-A10~17LF-LCPA User Manual antennas have to be installed in the same direction, please install them only after the signal quality is tested and the self-oscillation is avoided. If the directional antenna is selected, the main directional angle should point to the tower antenna. ⚫ If the performance is poor due to weak signals or poor phone call quality, please adjust the direction of donor antenna or change its position in order to obtain the best calling effect.
SZZJ-A10~17LF-LCPA User Manual If isolation can’t be achieved by the limited distance, the roof of the building or any other barriers can be used in between to increase isolation.

SZZJ-A10~17LF-LCPA User Manual Fix the donor antenna after selecting the best position, and adjust slightly its height or angles in order to get the signals with suitable input power level and calling quality. ⚫ System Requirement of GSM or PCS 1) The total input power level shall be around -50dBm, lowest shall be more than –80dBm 2) Test by mobile phone or data card by 3~5 times to make sure the calling quality is good at 95% of the time, and no handovers.
SZZJ-A10~17LF-LCPA User Manual 7) Take lightning protection measures for the antenna and feeder system in accordance with the design requirement. Avoid deforming the antenna feeder where grounding clips are placed, and give waterproof treatment to the feeder. 8) Keep exposed indoor cables in good order. Install PVC troughs or tubes if the exposed cables are more than 1 meter long. Place small passive RF parts such as power splitter in cable troughs.
SZZJ-A10~17LF-LCPA User Manual 2) It is better to use a directional panel antenna or Yagi when the coverage shape is long and narrow (corridors, long row of houses in two sides, tunnels or elevators or rural open space). 7.7. Repeater Installation 7.7.1. Installation Steps 10dBm~30dBm shall be installed in indoor areas only 1) Connect the power supply and the cables properly to the repeater ports. 2) Check again to make sure the repeater is installed firmly and repeater alarm LED must stay green. 7.7.2.
SZZJ-A10~17LF-LCPA User Manual impedance of coax will put an extra load on your repeater, shorten its life span and decrease the system performance. 7.8. Repeater Settings Please check very carefully all cable connections are correct and firm before running operation test and then carry out following tests. 7.8.1. Switch on power After power is on, check first the POWER and ALARM LEDs.
SZZJ-A10~17LF-LCPA User Manual ISO Display It is working with deep isolation Red Please adjust the distance/angle of the donor antenna and service antenna to keep with enough isolation. The longer distance, the better isolation. 7.8.2.

SZZJ-A10~17LF-LCPA User Manual ⚫ Setting of “edge point”: Switch on the power supply after connection with donor antenna and server antenna, and observe ALARM LED. ◼ If it shines “orange”, use 1dB as step to reduce the gain until “green” turns on, then increase the gain 1~3dB attenuation value until “orange” starts to turn on, then brings back 1~2dB till “green” is on, then fix the gain and the repeater’s downlink output power reaches the perfect status. ◼ If it shines “green” then.
SZZJ-A10~17LF-LCPA User Manual ◆ The weak input signal leads to the low output power. Change the direction of donor antenna or its installation position or replace donor antenna with higher gain antenna to increase input signal power level. ◆ Check whether it is necessary to add more server antennas since barriers block the signal penetration, also check whether the repeater’s power is enough; please install more server antennas or replace with a repeater of higher power level.

Repeater can not communicate in Power-ON status 1) The power is on but it has a signal fluctuation or a flash signal. The phone call can not be achieved. It shall be caused by the insufficient isolation between donor antenna and serve antenna. Please take below measures: ➢ Firstly check whether the alarm LED is orange. The orange light shows the insufficient isolation.
