The Shakespeare 4187 is a stainless-steel ratchet mount that lets you set the antenna angle and lower it when you need clearance, packaged for replacement or new installations.
Who it’s for
- Replacing a corroded or broken ratchet mount
- Boats that need to fold the antenna down
- Owners who want stainless over nylon
Key features
- Stainless-steel ratchet design
- Adjustable antenna angle
- Folds down for clearance
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.
