Shakespeare VHF 4' Phase III Marine Antenna – 6400-R
The Shakespeare 6400-R Phase III Antenna is a compact, high-quality 4-foot marine VHF antenna designed to deliver reliable communication performance on boats where space is limited. Ideal for small powerboats, sailboats, center consoles, and cabin cruisers, this antenna provides clear VHF transmission and reception for safe and effective on-the-water communication.
Built using Shakespeare’s Phase III™ construction, the 6400-R offers enhanced efficiency and signal clarity compared to standard short VHF antennas. Its 3 dB gain provides balanced performance for both transmission and reception, making it well suited for inland waterways, near-shore cruising, and day boating.
The antenna features a durable fiberglass radome with a sleek white finish that resists UV exposure, salt spray, and harsh marine conditions. Lightweight and rugged, it is designed to withstand vibration and continuous use. The 6400-R is compatible with standard marine VHF radios and mounts easily using common marine antenna mounts (sold separately).
Trusted for decades, Shakespeare marine antennas are known worldwide for their reliability, performance, and long service life.
Key Performance Features
-
Silver-Plated Elements: Maximizes electrical conductivity and range while resisting internal corrosion better than standard copper.
-
Foam-Filled Radome: The internal cavity is filled with specialty foam to prevent moisture buildup and eliminate "ringing" or mechanical failure in high-speed, high-vibration applications.
-
3dB Gain: Provides a broad, hemispherical signal pattern, ensuring your signal reaches the Coast Guard or other vessels even in rough, choppy water.
-
Stainless Steel Ferrule: An aircraft-grade 1"-14 thread mounting sleeve provides a rock-solid connection and a streamlined look.
-
Lightning Protection: Designed with a DC Grounding system to bleed off static and protect your sensitive VHF radio electronics.

Instruction Manual
Note: The 6400-R utilizes an SO-239 connector tucked inside the base. This allows you to choose your own custom length of high-quality coaxial cable (sold separately) rather than being stuck with a pre-attached length.
Because this antenna uses a "quick-connect" SO-239 base, it is the perfect time to use low-loss RG-8X cable. I can help you calculate the exact cable run length and connector types you'll need for your console.
The Shakespeare VHF 4' Phase III Antenna – 6400-R is an excellent choice for boaters seeking dependable VHF communication in a compact, space-saving antenna design.
