I put mine about 11 feet off the water. High enough to be well over
our heads in the cockpit, but low enough so sea clutter doesn't bother
a lot. I did this first after using the same kind as my first radar on
a friend's boat. He had it mounted on the mast, about 20 feet up. The
clutter really was a detriment.

I have JRC 1000 mounted about 3 meters (~10 feet) above the water. I can see
big ships at 6-8 nautical miles range and I consider it enough. On the other
hand, I can see little buoys at 0.2 nautical miles and it is enough too. In
general I am very pleased with my radars performance.

I have used both the 2kw and 4kw Raytheon radars. The 4kw gives brighter and
better defined targets than the 2kw. It will pick up small bay bouys at 1-2
miles where the 2kw won't pick them up until within 1 mile.

With your 4kw unit at the 1-2 mile range what roughly are the size
of the buoys
you can pick up and at .125 of a mile what would be the smallest
object you would detect.
