Keep Your Antenna Pointing True — Even When the Boat Isn’t
The Scanstrut LM-GPS Self-Levelling GPS/VHF Antenna Mount solves a problem that fixed mounts can’t: keeping your antenna vertical when the vessel heels, rolls, or is installed on an angled surface. As the boat moves, the self-levelling mechanism continuously compensates — so your GPS or VHF antenna stays optimally oriented for signal reception, regardless of what the sea or the deck angle is doing.
For GPS antennas in particular, maintaining a level, upward-facing orientation directly affects fix accuracy and satellite acquisition. For VHF, a vertical antenna radiates its signal in the correct horizontal plane — tilt it and you lose range in the directions that matter most. The LM-GPS eliminates both problems with a single, elegantly engineered mount.
Built to Scanstrut’s professional marine standard, it’s designed for permanent installation and long-term reliability in saltwater environments.
Key Features

- Ideal for angled deck surfaces where a fixed mount would leave the antenna off-vertical
- Professional marine-grade construction — built for permanent saltwater installations
- Clean installation profile consistent with Scanstrut’s mounting system
- MPN: LM-GPS
Specifications

🔧 Parts Desk Insights
Best use case: The LM-GPS is the right choice for two specific scenarios. First, sailboats — where the vessel regularly heels under sail and a fixed-mount GPS or VHF antenna is constantly off-vertical, degrading both GPS accuracy and VHF range. A self-levelling mount is the correct solution here, not a workaround. Second, powerboats and workboats with angled superstructures or coachroof surfaces where the only practical mounting location isn’t flat — the LM-GPS lets you mount on the angle and still have a vertical antenna. It’s also specified on some commercial vessels where antenna orientation is a regulatory or operational requirement.
Heads up: If your mounting surface is flat and your vessel doesn’t heel significantly, a standard fixed mount like the Scanstrut RA-01 Rail Mount will serve you well at a lower price point. The self-levelling mechanism adds value specifically where deck angle or vessel motion is a real factor. For full levelling range and compatible antenna thread specs, consult the Scanstrut LM-GPS datasheet or contact us before ordering.
