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?

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

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
