Saintly Fish Posted January 10, 2021 Share Posted January 10, 2021 Seeing as I have my radome on order, I’m also thinking about an eco max mini deflector. Question is, can I sight it right next to the radar either to the left or right of it? As king as it’s not forward of it, it should be ok ??

Odyssey Posted January 10, 2021 Share Posted January 10, 2021 (edited) Ideally above your radar Can you not get a dual layer strut made up? Or just go for an arch.... Edited January 10, 2021 by Odyssey JonC 1 Quote Link to comment Share on other sites More sharing options...

As the radome casts forward why can’t they sit side by side ? Anyway, is my boat mass not enough to be picked up by another boats radar? Or does the reflector just boost a detection?

GPSguru Posted January 10, 2021 Share Posted January 10, 2021 I would have thought that most of the radars were 'programmed' not to react to 'close by' reflections (reflections within a few metres)? ......... I don't have radar but my echomax is mounted on the side of the A frame and only just above the tubes. We have tested it with another boat, and he could see me at well over 4 miles away .........

Odyssey Posted January 10, 2021 Share Posted January 10, 2021 Your boat is GRP, you’ll just be scatter on a radar.... head out and ask a mate with Radar to ping you and see if you show up.... Quote Link to comment Share on other sites More sharing options...
captin slows old outlaw Posted January 10, 2021 Share Posted January 10, 2021 have a look at the boats in the mariner ? i think jon c is tring to sell you an arch becouse he ceeps arching on about it he he sorry i know that was bad, but im just board Quote Link to comment Share on other sites More sharing options...

Geoff Posted January 11, 2021 Share Posted January 11, 2021 (edited) Neil, revert to your plan A (staying moored on the pontoon). That would save a heap of money, remove the need to re route the aerial cable and stop the cushions getting smelly!!! If you want a bit of bling you could of course strut mount a radome enclosure.

Scotch_Egg2012 Posted January 11, 2021 Share Posted January 11, 2021 Pretty sure most radar doesn't just look forward, mine gives a 360 view around me. I mounted my radar deflector above the radar Saintly Fish 1 Quote Link to comment Share on other sites More sharing options...
Maverick Posted January 11, 2021 Share Posted January 11, 2021 Mine is located under my radar arch with radar above giving radar a clear view all around. I wouldn't place a largish object in my radars field of view (which is all round) above or below is the way to go imv Saintly Fish 1 Quote Link to comment Share on other sites More sharing options...

It does give an all round vision, it’s not just a case of looking for a blob on a screen on your heading bearing.... anything that is moving closer to the centre (you) is of worry.... Especially if you’re a WAFI doing 4knts and you got some hooligan in a fishing boat coming at you at 25knts..... 😁😁😁😁😁(Which is prob most of us at least once....) 🤣🤣 Quote Link to comment Share on other sites More sharing options...
Popular Post Odyssey Posted January 11, 2021 Popular Post Share Posted January 11, 2021 23 minutes ago, JonC said: You did a radar user coarse recently didn’t you? Is there any little too tips that everyone gets wrong? Tip No 1: Turn it on..... it’s there to be used not left to look pretty. You can gurantee that if you need to use it and it’s only been on once or twice it will be as much as use a chocolate tea pot Tip 2: train in good visibility. Worn out what boats look like in real life and on a radar screen. If you do this is good weather you’ll soon understand what real objects are when the fog comes down... Tip 3: Radar is giving all around range, not just straight in front of you. If you see a target on your screen, watch it. Does the target move closer to the centre? if so you are likely on a collision course. If it stays the same distance, you are fine. If it moves further away even better. Tip 4: if you do have a target that is not getting closer or further away from you then that means you are moving at the same speed relative to each other. However, they can change course or speed so be aware of this.... Tip 5: Read the manual. Yes it’s an exciting toy, it’s got lots of buttons and a nice coloured screen.... but read the manual and have a play, work out ranging, head up vs North up etc (Head up for collision avoidance, North up for plotting position) Tip 5: radar is highly accurate on range, however it’s not perfect on bearings. This is explained better on the RYA course.... Tip 6: best collision avoidance too is Mark 1 eyeball. Radar is a tool. Yes use it but don’t just stare at it and that alone as you flatten windsurfers, kayaks, sailing boats, Fishy (as he didn’t fit his reflectior) suzook12, Scotch_Egg2012, JonC and 2 others 2 3 Quote Link to comment Share on other sites More sharing options...
GPSguru Posted January 12, 2021 Share Posted January 12, 2021 (edited) 7 hours ago, Odyssey said: however it’s not perfect on bearings. That will be due to the scatter effect of the RF signal, it would be made worse by any obstruction within the fresnel zone. As we all know the bearing is the angle between North and the target, and its accuracy depends upon how North is defined by the Radar unit. Most modern Radars will use GPS to define North or a gyro signal is used where azimuth stabilization is used. The accuracy of a well setup system can be as good as +/- 1% . It is 20 years or more since I played / worked with radar, so I guess even the pulse radars of today have come on a long way since then ......... Doppler direction finding is more my bag .........

Sounds about right 🙂 Just avoid using radar for your 3 point fix.... 😉 Instead fix your position by range to known objects/landmarks and depth to work out your position. I’d did ask in my training as to why I’d do that given that both radar and depth are fed into the same MFD that is my plotter.... the response was that GPS satellites may have stopped working..... so I won’t go into too much detail about navigating using radar as I’m not sure it’s needed..... 😉 JonC 1 Quote Link to comment Share on other sites More sharing options...

Remember that your radar looks 360 degrees around the boat, so your ehcomax should either go above the radome or below the radome. On the RIB mine is down low and just above the tubes, but works absolutely fine ............. the ehcomax is classed as one of the best on the leisure / small professional market and does provide a good solid taget, therefore mounting position is probably less important than with octahedral (rain catchers\) type products. Here you can see mine on the stern starboard side. Edited January 12, 2021 by GPSguru Saintly Fish 1 Quote Link to comment Share on other sites More sharing options...
