What This Part Does
The Seaview AMA-W is an adjustable leveling wedge designed to sit beneath Seaview low-profile dome adapters and 8" round-base mounts when the installation surface is not flat. Two concentric rotating wedge halves provide up to 12° of angle correction, allowing the dome or antenna to sit level on sloped hardtops, radar arches, cabin tops, and other angled mounting surfaces without custom shimming or modification.
This is a mounting accessory only — dome adapters, mounts, hardware, and electronics are sold separately.

Installation Notes
Install the AMA-W beneath the compatible Seaview low-profile adapter or 8" round-base mount. Rotate the two wedge halves relative to each other until the required leveling angle is achieved, then verify the dome sits square and level from multiple directions before final tightening. Confirm cable routing through the mount and ensure the completed installation has appropriate support, weatherproofing, and clearance for the electronics being installed.
Service Interval
Inspect at each dome service or whenever the adapter is removed. Replace if cracking, UV degradation, or physical damage is present. Check all fasteners and sealant at the mounting surface annually.
Technical FAQ
How much angle correction does the AMA-W provide?
The AMA-W provides 0° to 12° of adjustment by rotating the two concentric wedge halves against each other. This covers most installation slopes encountered on radar arches and hardtops.
Can this wedge be used with all Seaview dome adapters?
The AMA-W is specified for Seaview low-profile adapters (AMA-16, AMA-18, AMA-18IP, AMA-24, AMA-32, AMA-GXF) and 8" round-base Seaview mounts. Confirm compatibility with your specific adapter model before ordering.
Is the AMA-W included with the dome adapter?
No. The AMA-W is sold separately as an optional leveling accessory. If your mounting surface is flat, you may not need it. If your surface is sloped, the wedge eliminates the need for a custom shim.
What hardware is included with the AMA-W?
The AMA-W is the wedge assembly only. Confirm hardware requirements with your Seaview adapter installation instructions.
Parts Desk Insights
The AMA-W is the part that makes a dome installation look intentional on a sloped arch or hardtop. Without it, a dome on a sloped surface either looks visibly tilted or requires a custom wood or aluminum shim — neither is a clean result on a quality electronics install. The most common issue is skipping the measurement step: check the actual slope angle of the mounting surface before ordering to confirm it falls within the 12° adjustment range. On installations with steeper slopes, additional solutions may be needed. Also worth confirming: the bolt pattern on the AMA-W aligns with your specific Seaview adapter model before committing to the installation.
