This antenna is designed to be used in places where UMTS signal level is to low and doesn't allow correct voice and data transmission through the modem. UMTS PANEL MIDI antenna allows to get better radio signal used in UMTS(G3) transmission 1900-2100 MHz. Using the antenna connected to the modem allows higher tramission speed due to better signal level and modulation. The antenna was made from the very best materials and is fully weatherproof (humidity, wind, UV).
Notice! To cooperate with GSM networks, the antenna should be set in vertical polarization!
