Default Radar Mounting Wedge Question

Going to put a wedge under the existing 25k radar open array. Is there a connection point at the array so I can disconnect and then reconnect or is the connection fixed permamently?
Furuno

It would help to specify the manufacturer of the array, but the answer is almost surely yes. I know Northstar's 25kw open array (no longer sold) had a harness that was run through a cable gland and connected within the housing of the scanner. I've wired smaller radars from Raymarine and Furuno, and they also have harnesses that attach within the housing. Otherwise you'd have an awfully tough time making your wire runs to the helm or whereever the processor is located with the connector end of the harness.

Skip,
should be easy to open the array up - usually hinged at one end or the other, and you can see where the wire harness comes in and connects. Take a few close up pictures of it before
disconnecting any wires so you can refer back to them.

The Furuno 6kw I have is pretty simple to you should be fine with the big boy. I plan to do a wedge soon as well. What degree are you going with? I was looking at making my own or the PYI? I think it is 4 degrees. Take some pics.

VC,
Will check the array out and see if it is hinged. If so will get some pictures.

Skip - why are you putting in a wedge? Is your running attitude that high that you need to angle it down? Most open arrays (and domes for that matter) have a 25 degree +/- vertical beamwidth. Or is it 25 degrees either side of the center. Regardless, most can reasonably take a moderate bow rise as coming up on plane with minimal degradation.

Are you noticing significant target loss as you come up on plane? Or is it just to make it look better.

Joe, When running I can pick up targets at 6 miles but start losing them when I bring the scale down to 3 miles or less. I'm losing about 30 degrees on each side of centerline. If I turn the boat to the side the target will start coming back into view.

Skip, that is wild. The changing the scale on the radar causes you to lose targets ahead, but you pick them up when broadside. Does this happen when off plane too? When on plane, what kind of angle are we talking about? Are there any interferences in front of the antenna (like a hardtop or something)?

Just installed a furuno 6kw open array myself. Removed some screws and top hinges open. Wire harness connects via multiple "din" type plugs except for ground. Clean gasket when done and coat with synthetic Ptfe grease. Silicone on screws and fittings.

Joe,
When trolling sometimes you can get the birds at 3 miles. Not really sure what angle I need but will probably start with 4 degrees. I also believe that my fuel has a bearing on the angle. When full fuel 700 gls under cockpit vs 1/2 tank is a lot of weight difference. I have a spotlight and Flir in front of the radar but it doesn't interfere. It might if angled down more but I think it will be okay.
