MRA45 maritime satellite antenna is compact yet high-performance system suitable for boats up to 30 feet.

The cassegrain antenna receives signals from most of the satellites inside coverage area. With the integrated GPS, the antenna can adjust its LNB skew angle automatically. The antenna can receive upto 16 different satellites.

Dynamic Skew option is a feature controlling skew angle dynamically with the help of a third gyroscope so that it performs as third axis control. It provides stabilised skew angle so that the antenna can work in wavy sea conditions as well.

SIS is Satellite Identification System, it comes as a standard feature to identify the satellite with “Digital Satellite Signal Processor” by analyzing the satellite data.
