This antenna is designed to be used in places where GSM signal level is to low and doesn't allow correct voice and data transmission through the modem. GSM PANEL ULTRA antenna allows to get better radio signal used in GSM transmission 900/1800 MHz. Using the antenna connected to the modem or telephone 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!
