SiSo Rooftop Antenna
The SiSo Rooftop Antenna series has been designed specifically for use on trains, trams and buses.
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.
