Look for signal amplifier input up to -50 DBM,This mobile phone signal works best。

A. Check if the upstreampower of the amplifier is normal, or the signal of the outdoor antenna is tooweak.B. First determine themobile phone signal at the outdoor antenna and reach (-50DBM) full grid.C. Make sure that thedistance between the indoor antenna and the outdoor antenna is more than 10 meters.It is best to isolate the indoor and outdoor antennas from the wall. If not,please change the po...

A. Determine the signal strength of the outdoor antenna (usually not less than -50DBM), check whether the display shows full grid, the stronger thesignal input, the stronger the amplifier input, no signal input amplifier, orthe input signal is weak, the amplifier input signal is also weak, Or nooutput.B. Make sure that the length of the outdoor antenna tothe amplifier circuit does not exceed 50 me...

A. Change the installation position and direction of theoutdoor antenna.B. Change the direction of the outdoor antenna to theamplifier signal transmission line (choose the straightest and nearestroute, do not turn too much).C. Make sure that the distance between the outdoorantenna and the indoor antenna is too close (too close to form aself-excitation), and that if the distance is more than 20 met...

A. determines that the outdoor antenna is aimed at the base station. B. determines that the communication distance between the outdoor antenna and the base station is within 5 km. C. determines that the cables of the outdoor antenna and amplifier are not more than 40 meters, not less than 10 meters, and confirm that the cable is up to the standard. D. If has not bee...

A. first determines that the outdoor antenna terminal has cell phone signal and reaches (-50dbm) above. B. re determine amplifier, antenna and other related parts. C. confirm that all lines, distributors, antennas and amplifiers are connected correctly.
