I do not think it is necessary for radar
to have such a large range, I find the selection more interesting according to its power consumption
You have two options with the radar
1) - Buy only the radome and use O. In this case make sure there is a plugin available and tested for that model. That can be laborious if you use other networks with the same PC or RPI.
2) - Buy the radome and the MFD from the manufacturer. In this case, check the MFD documentation
to see if it sends ARPA / MARPA sentences, either by NMEA0183 or NMEA2000. So you can see the targets in O and in other mobile apps.
