I have a sailing boat that will sail heeled at 20 deg very often. I want to know if the radar image will be satisfactory at that heel angle?
The specification of the DRS4D-NXT is a +/- 12.5 deg vertical beam width. If all the radar beam is within that vertical beam width then when heeled at 20 deg I will have no returns to one side where I will have just sky and the other side will have no horizon and so limited returns.
Other radar makes give a percentage of their beam outside of this 25 deg vertical beam width, so what is the actual beam pattern on this model? Is there a radiation beam strength chart available? The Navico 4g for example specifies in their installation manual that 100% of beam power is within a 50 deg vertical beam spread of which 50% is in the central 25 deg spread.
