Radar That Stays Level — No Matter the Conditions
The Scanstrut Self-Levelling Radar Mast Mount keeps your radar antenna locked on the horizon as the boat rolls and pitches, delivering a consistent, accurate radar picture when you need it most. Designed for mast installation on powerboats, motorsailers, and vessels without a backstay, it positions the antenna high and clear of deck obstructions for maximum range and a full 360° sweep.
The self-levelling mechanism works continuously and passively — no electronics, no calibration — so your radar performs at its best regardless of sea state.
Key Features
- Continuous Self-Levelling — Passively keeps the radar antenna level with the horizon through roll and pitch, preventing target loss and maintaining picture quality in rough conditions.
- Mast Mount Design — Attaches to the mast for a high, unobstructed antenna position with a clear 360° radar sweep and a clean, uncluttered deck.
- Broad Vessel Compatibility — Suited to powerboats, motorsailers, and any vessel where a backstay mount is not practical.
- Optimised Antenna Performance — Eliminates signal degradation caused by a tilted antenna, giving you the best possible radar return at all roll angles.
- Passive Operation — No power or electronics required for the levelling mechanism — nothing to fail, nothing to calibrate.
Compatible With
Designed for use with dome and open-array radar antennas. Check your radar manufacturer’s specifications for maximum antenna weight before selecting a mount.

Parts Desk Insights
For in-store reference only.
- Best Use Case: Ideal for powerboat and motorsailer owners who experience radar picture degradation due to vessel roll, and want a mast-mounted solution that self-corrects without any electronics or active components. Also the right choice for sailboat owners without a backstay who still want self-levelling performance.
- SKU: 922-LMM1
- Key Differentiator vs. Backstay Mounts: Mast mount is the correct choice when there is no backstay (powerboats, motorsailers, fractional rigs). Backstay mounts (922-LMBA1 aluminum, 922-LMBF1 fibreglass) are for sailboats with a traditional backstay.
- Passive Levelling: No power connection required for the levelling mechanism — a strong selling point for customers concerned about wiring complexity or electronics reliability.
- Weight: 5.9 kg — lighter than the backstay variants (11.34 kg); confirm radar antenna weight rating before recommending.
- Pair With: Consider recommending the Scanstrut PTMR11 Tapered Radar Mast for customers who need a complete mast solution.
