I tried to find any specification throgh the local dealer, and he did
not even get an answer at Sea Ray in the States (neither yes nor no,
essentially along the lines of we do not supply it so we do not know):

I would like to have a 4'/22kg Radar antenna on a Sea Ray 315 Sundancer
Sport Spoiler, Molded Fiberglass (Seamless) w/Overhead Lighting.

Is this workable, as I do not seem to get an answer from SeaRay?
Or is there a lower weight limit so I would have to forego the
advantages of a big enough antenna?

TIA

Marc, let's take a look at reality on radar......

Radar cannot see further than the horizon.

The horizon depends on how far UP the antenna is mounted.

From your SR31, we're up just above the flybridge. How far can YOU see
with binoculars...6 miles? 5? Check it out.

If we had a 500KW military surface search radar on your arch, it could
"see" targets 6 miles away....maybe 8 or 9 if they are TALL targets like
lighthouses, radio towers, etc. So, what's the point?

You're not as tall as a containership, who can use a more powerful radar.
So, why waste money on HIS radar transceiver??

From up there, how about the 4KW radome? Loading on both the arch and
your electrical system are lots less, also your wallet. 4KW has no
trouble making a target at 8 miles. Ours is only 2KW on the sailboat,
but we don't have it high up because if you put the antenna up high you
CANNOT SEE THAT DAMNED BOUY YOU ARE ABOUT TO RUN OVER IN THE FOG because
the high antenna is shooting right over the top of it. Ours is up 35' on
the mizzenmast, probably higher than your arch. It can see the dock 3
slips away, plenty of return from that bouy in the fog.

I know the big swinging radar horn impresses the other sailors and looks
cool like you're an aircraft carrier....but why?....(c;

Besides, you're not going 400 knots like a jet. If you can see targets 2
miles away you have MINUTES to turn away...not seconds. That's far
enough for collision avoidance isn't it?

Though you might not see targets farther, with a larger antenna you would
have a better resolution, and that would be a good thing, don't you think?

Poor baby. Some of us speak and read more than one language. You should
have paid attention in school. Last time we were in Mexico, we spoke
"schoolbook" Spanish for the first few days, and then managed to pick up
on Mexican Spanish enough to feel at ease.

But you understand English.........right?

My grandparents (both sides) learned English when they came over. They also
came over legally, as did millions of other immigrants.

Folks with your type of thinking have ruined America and the future quality
of life for my children, grandchildren.........etc.........

I feel sorry for them based on the world they will be living in.

Thanks Harry.

I've been visiting Florida for decades, starting in the 1960s. The first
time we went to Miami, I practiced my high school Spanish down there.
People speaking Spanish is nothing new. There are just more folks doing
that now. When we lived in Florida, and it was North Florida, we spoke
English and Spanish, and English mixed with Spanish.

Americans are intellectually lazy. An awful lot of those born here with
"anglo" parents can barely speak or write plain high-school level
English. No wonder they can't pick up a little Spanish, eh?

Your boy Bush has done nothing to close the leakage at the borders for
the past seven years. He's your boy...why isn't he doing what you want?

What's your point? Your response has nothing to do with the sig.

That is true. If you have a huge antenna, you can see whether it's one
ship or 8 ships close together. That might be important for missile
launching, but does it really matter in a boat? INstead of 3 tiny targets
on the tiny screen...you get one big blob you can't miss on the cheap
antenna. Too much resolution isn't a good thing on a small boat whos
antenna is rolling and pitching so awful in the swells.

Basically it boils down to: The higher the frequency of the beam, the
higher the frequency of the PRF (Pulse Repetition Frequency) and the
shorter your pulse length the better your resolution. Antenna size only
affects the signal strength the receiver sees, for the most part. Which
is assuming it's built for the proper frequency.

I was on an ancient AD (Destroyer Tender, built during WWII, USS
Arcadia) and had a helluva discussion with a WO who was doing the CIC
thing when we entered the Chesapeake Bay and why the old radar wouldn't
enable me to determine where the bogey I was tracking went into and out
of a glob of traffic. Also he was sure I should be able to pickup
dolphins since the radar beam went over the edge of the ship, made a 90
degree down angle turn, another 90 degree angle turn at the surface, and
shot out over the surface. To was repeated for the echo. This on a
ship where the repeater would drop out because the AC volts supplied
dropped below 90.

of stuff.
