Shenzhen Safe Guard Co., Ltd

long range tactical signal sender 5km NLOS cofdm transmitters
Model: SG-S20

This military backpack system is special for man-portable transmitter enter into the area of the incident to gather information and signal transmission when in the condition of heavy obstacles,such as many building barriers ,severe electromagnetic interference,remote mountain town or other harsh environments, which cause command vehicale can’t directly reach the site and forced to parked in vicinity.
