Stern mount open array

I'm seriously considering installing an open array (Simrad Halo) on a stern pole for my 43ft sloop. Primary consideration is squall tracking.

Anybody have experience with stern-open array and the effects of heeling with regards to effectiveness?

Re: Stern mount open array

Squall tracking can be done well with the smallest cheapest radar you can buy, if that is all you want. Those old little JRC1000's will do It just fine. It is probably the easiest thing for a radar to do. A large open array system is overkill.

Now, punching through a squall to see things within it is an entirely different trick...

Re: Stern mount open array

So a regular mast mount 4G dome would be what you recommend? We're brand new to cruising and have an old Furuno dome on the mast, but unfortunately, it's a big CRT at the nav station and not visible from the helm. I want to upgrade to a system that will display on the Zeus2 plotter at the helm.

I second what Mark says. I would get a 24km radome and combined color chartplotter/radar with a good rate sensor (for accurate chart/radar overlay). I like Furuno but there are several good ones. Up on your mast is best for range but you can do fine with a stern mount too. Squalls are easy to spot from a distance. I would add AIS too while you are at it (like the Vesper) and integrate it with your plotter (or to another display).

Or seeing what is on the other side of it.
Hint, the Mother of all Squalls

Re: Stern mount open array

You want to integrate it into your Zeus, so I'd go with a 4G over a 3G.
If you have a pole on the stern I'd mount it there, mine is, and I see no disadvantage.
I don't know how much heel it takes to degrade the Radar, good question though, I'd assume effective beam width would be the answer?

Re: Stern mount open array

I have the 4G radar, and I like it, but squall detection is not its forte.

Re: Stern mount open array

4G or 3G? Isn't the only difference between them Maximum Range?

AFAIK the difference is all software, but 4G has "beam sharpening" and so better target discrimination, and a couple other features. Supposedly.
