Responding to abusive, wrong-headed posts from alias-Wilbur is very much
like banging one's head against a wall for fun - but I'll do it any way.

Radar output is the transmit power from the magnetron.
This pulse lasts 1 microsecond or less, and can be repeated 1000 times
per second. 2.2 kW power for say 1 microsecond X 1000 per second gives
AVERAGE power of 2.2 watts - but there is the processor, the display
etc., etc so 20 to 30 watts while transmitting is in the ball park.
A coupla amps in fact.

I expect there was SOMETHING correct in alias-Wilbur's post, but I
didn't look at it that closely.

Not bull! Fact!

If you run radar you are motoring because the damned things draw so much
power. Since you're motoring you are no sailor.
False.

My RADAR draws slightly over 2.1 amps MAX. Over 10 hours of normal
use, it draws an average of about 1/4 to 1/2 amp, or 3 - 5 amp hours
in a 10 hour day. It is really even be less than that. I have a
dedicated AGM battery for just the RADAR and a small 20 watt solar
panel has no trouble keeping it fully charged regardless of how much I
use the RADAR.



LIAR! Volts X Amps = Watts.

So if your unit draws 2 amps that means your unit has a puny 24 or so watt
output provided it it 100 percent efficient which it is NOT. Hell, a VHF
radio outputs at 25 watts and it has no moving parts.

That means your pitiful 2.1 amp radar is good for a range of maybe a 1/10
mile. Waste of time and space, dude! Freaking TOY!

Here's a link to a compact yacht radar:

Note the output is 2.2 KILOwatts.

Using the above formula, V times amps = watts, you get approximately 14
amps.

You're even more clueless than poor Skippy!
