gsm 900 mhz rf Band Selective Cellular Repeaters/booster /amplifier

  Product Description     43dBm GSM900 rf 20W Band Selective Cellular Repeaters/booster /amplifier (KT-GRP-B25-P45-B) 1) Improve Cell Phone communication;
2) Reduce radiation from Cell Phone;
3) Easy to install; 4) OEM Manufacturer ,customized available   High Power GSM RF Repeater,GSM900 rf Band Selective cellcular Repeater booster/ amplifier   Application:      Repeater is to provide a rf High Power GSM RF Repeater,900 rf Band Selective cellcular Repeater booster/ amplifier dio coverage in a flexible and efficient way. Among the things with reference to the design it can be difficult to spread coverage all the way into side isles, narrow hallways, several storys, combined with different building materials. More over, if there are many people constantly moving, for instance in shopping malls, and the demand for coverage varies from one spot to another as well as during the day and during the week, satisfying the growing demand for capacity becomes a challenge. The same storys can been occurred in some villa group, Subway, Speedway, etc. So the repeater can gives you the optimal solution.    To expand signal coverage of fill signal blind area where signal is weak or unavailable.    Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.    Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc.    It is mainly applicable to such case:    The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx  Level in repeater site should be more than -70dBm;  And can meet the requirement of antenna isolation to avoid self-oscillation.    GSM900 broadband cell phone wireless RF Repeater Function:   Waterproof chassis suitable for indoor and outdoor service; Metal cavity filter technology inside, which gives wider receiving and sending separation, better gain flatness, higher stability, and lower noise figure; lFull-duplex & dual-port design, and built-in power supply, making it convenient for installation; Allowing for continuous gain adjustment and gain contrast; ALC technology used to provide auto amplitude fixing.  GSM900  broadband cell phone wireless RF Repeater Application: Outdoor:  Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.     Demensions and Weight:   Dimensions(package size): 750(mm)×500(mm)×310(mm) Weight:   N.W.29.5KG     G.W.32KG
