The Shakespeare 414 shim kit corrects the angle of a ratchet mount on a sloped deck or hardtop, so your antenna stands truly vertical, which is where it performs best.
Who it’s for
- Antennas mounted on curved or sloped surfaces
- Fixing an antenna that leans after installation
- Compound-angle installs
Key features
- Four heavy-duty rubber shims
- Front/back and side-to-side slope shims
- Each shim adds about 5° of tilt
- Stackable for more height or compound angles
Mounting tips
-
Check the thread. Most marine VHF, GPS, and TV antennas use a standard 1"-14 thread.
-
Plan the fold-down. A ratchet mount lets you lower the antenna for bridges, trailering, storage, and covers. Check clearance through the full swing before drilling.
-
Back it properly. An 8-foot antenna puts real leverage on its mount in wind and waves. Use backing plates or through-bolts on thin decks and hardtops, and bed fasteners with marine sealant.

Before ordering
Confirm compatibility with your ratchet mount, the correction angle you need, and that your fasteners are long enough with shims added.
