Self Levelling Radar Mount - Backstay
Our Self-Levelling Radar Mount range ensures your radar stays level with the horizon at all times for optimum antenna performance.
As the boat heels or rolls, the radar is kept horizontal preventing target loss and giving the best possible radar picture.
Our Backstay mounted version positions your radar away from any interference, leaving a clear deck free from obstruction.
- Hydraulic Damping
The main levelling unit features a fine turned damping system which reacts to major changes in heel angle of the boat. It is entirely maintenance free and no power is required

Some answers to frequently asked questions...Ask a question
F.A.Q.'s for Self Levelling Radar Mount - Backstay
Can this product be installed on boats with a split backstay or runners?
If backstay split length is less than 2.7m (8’10”) above the deck, you can mount the system centrally and attach head unit onto the central cable above split. Pole extensions available to raise antenna higher.
This is not really satisfactory in most cases because it will obstruct aft access to the bathing platform.
If backstay split length is over 2.7m (8’10”) above the deck, you can install the mounting pole and head unit parallel to lower backstay.
If the leveller pole is to be installed parallel to one of the ‘splits’, in most cases it will be difficult to correctly orientate the assembly (i.e. with radar and swing axis of leveller parallel with yacht’s centreline) using the supplied pole base bracket.
For a satisfactory install, a custom ‘wedge’ must be fabricated to go between the pole base bracket and deck. Another identical wedge will be required on the underside of the deck or transom to provide a perpendicular face for the nuts and washers. The wedges can be planed to the correct angle from a block of hardwood (teak or mahogany or similar). They need to be independently fixed to the deck with fasteners spaced differently to the pole base bracket, to stop it from squeezing out under compression.
'Split Backstay Fitting Kit’ available soon…….
This installation requires reasonable backstay tension. If you are likely to completely slacken off the stay during sailing, we recommend installing an alternative Scanstrut product (dedicated stern pole or mast mount).
How will the pole base bracket fit to my backstay chainplate?
You will have to drill and tap the chainplate to accept the 2 x M8 fixings that are supplied with the base fitting.
I am worried about my bimini conflicting with leveller installation.
The best thing to do is to check the technical information. This will show the clearance that you require fore of your backstay when installing the product.
My Raymarine dome does not sit level with the boat is at rest – why is this?
Do not worry, your leveller is still working. The dome’s centre of gravity is off centre resulting in a slight ‘list’ to one side.
Since we became aware of this issue we have offset the holes on the mounting plate and so the dome will now sit level. The new plate is available to purchase should you require it, please contact the Scanstrut sales team.
I have a hydraulic backstay adjuster – will I still be able to install the product?
The product is supplied with backstay bushings which clamp around the backstay. These mean that you can still adjust the tension of your backstay without the Self Levelling product getting in the way.
The maximum diameter for backstay adjuster unit is Ø60mm.
My backstay wire is ø6mm, do you do a head unit bush to accommodate this?
Nylon bushes are supplied for backstays from 7mm (0.2”) up to 14mm (0.6”). You will be able to use the 7mm bush for your 6mm dia. Backstay.
Is the Self Levelling Radar Mount suitable for choppy seas or racing conditions?
YES - The structural strength is exceptional in this product. Our design team completed a shock test on sailor Alex Bennett's boat, see what happened at: http://www.scanstrut.com/products/special-page.php?project_id=61
If i am using the backstay as an antenna for my HF radio, will installing the Self Levelling Backstay Mount interfere with this?
The kit is supplied with a nylon bush which fits around the backstay before you clamp the levelling head unit to avoid any metallic connection.
Just ensure that you do not fit the pole base onto the backstay chainplate.

I would recommend Scanstrut, 4 Aug 2010
By Barry & Dale Keith, Scanstrut Customer I assembled the support (Self Levelling Backstay Mount) and it went very well based on the instructions which were very clear.
I am very happy with the installation and I have had numerous positive comments from others. Thank you very much for your assistance and information which allowed me to plan the attachment to the chainplate. I will certainly recommend Scanstrut to others.
