SiSo Antennas covering all LTE, WiFi & WiMAX frequencies
The SiSo Rooftop Antenna series has been designed specifically for use on trains, trams and buses. Weatherproof and environmentally sealed to IP67, the SiSo antenna can maintain optimal performance in virtually any conditions.
The SiSo range covers 698-960/1710-6000MHz with optional GPS/GNSS with a 26dB LNA. The radiating element is DC grounded and, in versions with a GPS module it is protected by an integrated gas discharge surge arrestor. Housed in a high impact, flame retardant polycarbonate housing, the SiSo series is weatherproof and environmentally sealed to IP67, ensuring that the antenna’s performance is never compromised.
