Self-Levelling Radar Mount – Backstay
LMB-F1
Maximize your Radar's performance
2.6m (8’6”) high, mounts forward of the backstay, keeping your radar away from any interference, leaving a clear deck free from obstruction.
Constructed from the best marine-grade aluminium, designed to fit the most up to date radars from Garmin, Raymarine and B&G.
Hydraulic damping
The main levelling unit features a fine-tuned damping system which reacts to major changes in heel angle of the boat. It is entirely maintenance-free and no power is required.
Bespoke mounting pole

High strength universal base for mounting pole
Eliminates loading on backstay. The base can be deck, transom or chainplate mounted.
Suitable for any yacht
Stainless radome cradle has a fine tune adjustment for backstay angle and the product can be installed on both adjustable and split backstays (see faq for further information).
Nylon backstay bushing supplied
Clamps around backstay allowing cable tension to be adjusted.
Mount your radar higher
Additional 0.6m and 1.3m lengths available to mount your radome higher
Installation Guide
If you can't find the answer to your question, please get in touch and one of our product experts will get back to you.
How will the base fixing fit to my backstay chainplate?
Drill and tap the chainplate to accept the 2 x M8 fixings
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.
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. Max diameter for backstay adjuster unit is Ø60mm
My split 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.
Can this product be installed on a split backstay?
Option 1: If backstay split length is over 2.7m (8’10”) above the deck, install the mounting pole and head unit parallel to lower backstay
Option 2: If backstay split length is less that 2.7m (8’10”) above the deck, mount system centrally and attach head unit onto the central cable above split. Pole extensions available to raise antenna higher. If the the split backstay is ‘running rigging’ then can not be installed

To ensure the highest level of accuracy, testing is conducted both internally and by independent ISO accredited test houses.
This commitment to quality has earned Scanstrut the approval of renowned names such as Mercury Marine, Grady White Boats, Boston Whaler, Winnebago, Airstream and many more. To learn more about the SCA testing program and certifications, get in touch.

On Water Test
Dynamic on water testing in harsh coastal conditions. Mounted to a test vessel to evaluate its performance in rough sea states.
Shaker Table Test
Shock testing in X / Y / Z and +/- axis at 5G increments up to 30G to evaluate the products strength, particularly relevant for our Radar mounts.
Corrosion Test
100-hours of a special formula salt spray that simulates accelerated marine environmental effects on the product.
FEA Analysis
Finite Element Analysis, simulates the behaviour of the design in virtual conditions to allow us to optimise the design before prototyping and physical testing.
IP Test
Water and dust protection under test laboratory conditions to international IP standards. We test between IPX4 (waterjet) and IP68 (submersion).
30G Shock Test
Shock testing at 30G (30 times the force of gravity) to evaluate strength, particularly relevant for our Radar mounts and other powerboat products.
Impact Test
Drop tests to assess the impact of items falling onto our products and ensure they can withstand impacts while being used as intended.
Material Test
Positive Material Identification (PMI) ensures consistent quality of 316 Stainless Steel and Aluminium products. This controls strength and environmental performance.
PROP65
Confirms the exclusion of substances of very high concern in our products, with the aim of protecting human and animal health.Accessories
