Norway-based Comrod A/S has developed a new Multifunction Antenna System – MAS1. It allows simultaneous transmitting and multireceiving through a single cable and antenna – at the same time. Its ultimate compact design using latest technology makes the MAS1 unique compared to other multi-function antennas on the market. A regular COMROD VHF or COMROD combined VHF/cellular antenna is mounted onto a wide-band preamplifier (MAS1/A.BI). By this, all frequency bands are combined into one output port and only one antenna cable is required. At the other end of the cable, a filter unit (MAS1/F) is connected. This unit divides the signals into its desired connection port.
