Shakespeare Phase III 4 ft VHF Antenna with Ratchet Mount (SHA-6400-R)

The Shakespeare Phase III is one of the most trusted names in recreational marine VHF antennas — and for good reason. This 4-foot fibreglass antenna delivers reliable 3 dBd gain performance across the full VHF marine band, while the integrated ratchet mount allows the antenna to fold down flat for low-clearance passages, trailering, and storage. A practical, proven choice for powerboats, sailboats, and centre consoles of all sizes.

Key Features

• 3 dBd gain for solid VHF range on recreational and coastal vessels
• 4-foot (1.2 m) fibreglass construction — lightweight, rigid, and corrosion-resistant
• Integrated ratchet mount allows antenna to fold down and lock in multiple positions
• Covers the full VHF marine band (156–163 MHz)
• Standard 1–14 UNS thread base fits most marine antenna mounts and rails
• UV-stabilised fibreglass radome for long-term colour and structural integrity
• Shakespeare Phase III series — a benchmark in recreational marine communications

Ratchet Mount Advantage

The -R ratchet mount variant is ideal for vessels that regularly pass under bridges, enter covered slips, or are trailered frequently. The antenna folds down in seconds and locks securely at multiple angles — no tools required, no antenna to remove and stow separately.
