Model Number: CKJ-B02-20DB
Brand Name: CKJ
Key Specifications/Special Features:
Name:Dual band signal amplifier 20dBm GSM900MHz 3G2100Mhz black boosterModel: CKJ-B02-20DBproducts introductionIndoor dual band signal repeater (signal booster) series is an ideal solution for both two wireless system in small/medium businesses and home users looking to enhance indoor 2G&3G wireless connectivity. It is connected via coaxial cable to dual band donor antenna and service antenna, dual band donor antenna is placed outside the building where it has easy access to BTS signal, and the service antenna is placed in the building where it can extend radio coverage to the blind area. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument.The dual band improves mobile signals with no negative impact on human health.
Standard package:
1) AC90-264V, DC9V/5A power supply adapter 1PCS
2) AC power cord (EU/US/UK/SA/China standard, etc) 1PCS
3) Installation kit 1PCS
4) User manual 1PCS
Recommended accessories:
1)Donor antenna: Log periodic antenna (9dBi, 806-960/1710-2700MHz)
2)Service antenna: Omni ceiling antenna (3dBi, 806-960/1710-2700MHz)
3)5D-FB coaxial cable with connecter (cable length optional)
20dBm 900MHz+3G dual band signal amplifier/mobile phone repeater/cell phone booster(GW-20GW)
Features:
1. Cost effective solution for weak signal zones, reduce drop/off calls.
2. Compact size, low power consumption, easy installation, great cover.
Expansion and extension of the signal of base station. Optimization of the quality of the signal and source
3. Cover about 500~2500m Without block or obstruct.
4. High linear design, ALC function design, low interference to BTS.
5. Support any cellular devices (voice & data & video)
6. Wide band signal booster, or customize selective band booster.
7. Support system CDMA800, GSM, DCS, PCS, WCDMA, LTE 4G etc
Advantages:
1. Smart function, Intelligent mode setting
smart function called which can be activated via the front panel.
users can adjust gain and choose working band by LED panel, this smart function is easier than DIP switch, can set up parameters, it is a simple, safe and effective way.
2. Auto level control
The 30dB ALC is used to maintain steady output power even when the donor source signal fluctuates.
Application:
To expand signal coverage of fill signal blind area where signal is weak or unavailable.
Indoor: Hotels, home, basements, shop
