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.

Surely it depends on the voltage at which the 2KW beam is generated?
