J3F 23~27dBm Output Power, 75dB Gain
Introduction
Signalwing’s J3F series are designed for indoor application. It’s able to support any one of the popular mobile systems, and help consumers to improve the cellular coverage in houses, large building, pubs or underground parking lot with poor reception.
System status is clearly visible by LED indicators. The light weight and compact size make it easy installed. The coverage of J3F is ranging from 1000~3000 square meters due to different power level and input signal strength.
