* This is only a indoor/outdoor antenna which receive/transmit frequency, would not generate any signal. * Wide band 698-2700 MHz compatible for 2G/3G/4G LTE mobile signal booster. * Durability and Waterproof, both Indoor / Outdoor use are supported, wider coverage. * NOT WORK AS HDTV ANTENNA OR FM RADIO ANTENNA. * PLEASE NOTE THE CONNECTOR TYPE BEFORE PURCHASING.How to Use: 1. Outdoor antenna?Signal Booster?Indoor antenna, these three devices should be connected via coaxial cable(sold separately). The antenna itself doesn't produce much gain. 2. Antenna Placed is the higher the better. Also, you should find somewhere outdoor where the signal is stable to install. Electrical specifications: Frequency range (MHz): 698-960/1710-2700 Polarization: Vertical Gain(dBi): 6dBi Impedance(?): 50 VSWR: ?2.0 Maximum input power(W): 100 Lightning protection: DC Ground Mechanical specifications Connector: N Female Dimension(mm): 7.5x2.5x2.5 inch(Length*Width*Height) Antenna weight(lb): 1.1 Material: ABS Rated wind velocity: 60 km/h Ambient temperature: -40? to 140?/-40? to +60?FAQ: Question: After installing booster, signal not be very good, indoor signal coverage very small Solution:1.adjust outdoor antenna's location and direction 2.check whether cable connected well 3.put more higher receiving antenna's position, which can receive more good signal Question: Cellphone signal full bar, but communication quality bad Solutions: Too closer distance of indoor and outdoor antenna, need more separation far distance away between antennas Question: After installing booster, signal not good, but even worse than before Solutions: Too closer distance of indoor and outdoor antenna, need more separation far distance away between antennas
