The Shakespeare 4186BP (L206B) is a solid-nylon four-way ratchet mount for deck or side mounting, an affordable, corrosion-free base for most VHF antennas up to 8 feet.
Who it’s for
- Deck or side mounting on small and mid-size boats
- Budget replacements for a worn ratchet mount
- Owners who prefer nylon to avoid corrosion
Key features
- Solid-nylon four-way ratchet with handle
- Standard 1"-14 thread
- Bolt holes approximately 5/16" diameter
- Not for self-supporting antennas longer than 8 ft
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.
