Radar for Humber 6.3 m with single a frame?

[markalderney]

please advise on suitable radar kit to fit to a single A frame. weight is an issue.

Height will be as much an issue so you don't cook your eyeballs
What diameter is the tubing, and how is it fixed to the transom?

Not an issue with Broadband Radar

Let's see a photo of this A frame. Dr Doof on here had problems with his Humber A-frame cracking under the load of a radar dome. There's about 7kg of kit involved so it takes a lot of supporting...

Thanks, broadband radar seems the way to go. 2" stainless steel A frame fitted by Humber, hope the photo is useful? Mark

Mark, I have the Simrad 3G broadband radar on my a frame and it is low but not an issue. You may need to weld a flat plate to the top of your a frame

thank you, i will investigate the device ...weight may be an issue

I think that the single frame is the main issue. Hold onto the top and rock it backwards and forwards quickly - does it flex? If it does, I'd forget about adding 8kg to it...

Good point one needs to check the weight of the scanner. I think 8 kg maybe over the top.

A Broadband 4G™ Radar weights in at 7.4 kgs so my man willk is on the ball.

Personally I would be worried about the possible effect of the vibration that a single tube A-frame may create.

Also the radar array has to have a clear line of sight forward to be effective

I was adding the extra half kilo for steel plate and fixings.

yes i would agree here and I forgot that I have a solid double A frame. a single was is really only for top light , nav lights and VHF antenna.

You might want to discuss with Humber - you wouldn't want them suggesting the extra leverage is why the transom failed.
