There is something I dont understand about radars. I have a JRC 1500 radar
(16 miles), in according to the manual, the antenna is supposed to send out
a radarbeam of 2000 watt. My engines (yanmar 4lha htp) generator produses
12v 80A (1120watt).

I dont use the radar all the time, but if I did, would the engine be able to
produse enough power to my batteries?

Some experienced sailors say my radar cannot have an effect of 2000watt. It
is the same effect of an electical owen.
