The Original Shakespeare 393 SSB Radio Antenna is a reliable choice for HF/SSB radio communication needs in a marine environment. Designed for recreational boats, fishing vessels, yachts, and professional marine applications, this antenna offers robust construction, input power of up to 1,000 watts, and a wide frequency range of 2–30 MHz when used with a suitable antenna tuner.
With a total length of 23 feet (approximately 7 meters), the Shakespeare 393 supports more optimal long-distance communication. Its design is specifically built to withstand exposure to seawater, high humidity, salt spray, and the changing weather conditions commonly encountered during vessel operation.
Weather-Resistant Shakespeare 393 Marine SSB Antenna
SSB radio communication is one of the essential devices on a vessel, especially when long-range communication beyond VHF radio coverage is required. To support SSB radio performance, an antenna capable of handling high power, resistant to the marine environment, and able to operate across various HF frequencies is needed.
The Shakespeare 393 comes as an SSB whip antenna without a loading coil. The antenna's conductor uses brass and copper materials, securely protected inside a white fiberglass tube. This sealed construction helps reduce the risk of damage from corrosion, oxidation, moisture, and salt exposure.
For users who prioritize marine communication equipment with a practical design and stable performance, the Shakespeare 393 antenna is a solution worth considering.

These specifications make the Shakespeare 393 well suited for use with shipboard HF/SSB radio systems that require a long, strong antenna supporting high-power transmitters.
Advantages of the Original Shakespeare 393
2–30 MHz Frequency Range
The Shakespeare 393 can be used across the 2–30 MHz frequency range with the help of an antenna tuner. This range supports the use of various HF bands for SSB radio communication, including long-range maritime communication needs.
The tuner is essential because this antenna operates as a long whip antenna and requires impedance matching so the radio system can work efficiently on the frequency in use.
Supports Power Up to 1,000 Watts
This antenna can accept input power of up to 1 kW. This capacity makes the Shakespeare 393 suitable for marine SSB radio systems that require high transmission power to support more reliable communication.
The ability to handle high power also provides flexibility for vessel users operating communication equipment for navigation, fleet coordination, emergency communication, or long-distance communication at sea.
Optimal Antenna Length of About 7 Meters
With a total length of approximately 7 meters, the Shakespeare 393 has an ideal size to support HF radio transmission needs. This size helps produce good radiation performance without requiring an additional loading coil.
The absence of a loading coil helps keep the antenna construction simple and supports stable performance. The antenna uses a full-length conductor from end to end, allowing signals to be transmitted more consistently.
Full Conductor Construction
One of the key advantages of the Shakespeare 393 is its use of a full conductor running from the top to the bottom of the antenna. The brass and copper conductor is enclosed within a sealed fiberglass structure.
This construction supports radio transmission efficiency while protecting the conductive components from marine environmental exposure. For vessels operating routinely at sea, protection against corrosion is an important factor in maintaining the equipment's service life.
White Fiberglass Resistant to the Marine Environment
The antenna's exterior uses white fiberglass built for marine use. Fiberglass is known to be strong, lightweight, and resistant to outdoor weather conditions.
The fiberglass tube on the Shakespeare 393 also serves to protect the internal conductor. Because the conductor is sealed inside the tube, the risk of water, moisture, or salt entering the internal components is minimized.
Practical Three-Section Design
The Shakespeare 393 uses a three-section design. This 3-section construction makes shipping, storage, and installation more practical compared to a single-piece long antenna.
For vessel owners, marine technicians, and communication equipment distributors, the three-section construction makes handling the antenna during installation easier. Once assembled, the antenna still provides its full length of about 23 feet to support SSB communication performance.
Sturdy Base and Ferrule
This antenna is equipped with a chrome-plated brass base/ferrule with a 1"-14 thread. This material is designed to produce a strong mechanical connection to the vessel's mounting.
A stable mounting connection is very important because the antenna will face engine vibration, wind gusts, vessel movement, and sea conditions. Make sure the mount used is compatible with the 1"-14 thread and is installed correctly to maintain system safety and performance.
Applications of the Shakespeare 393 SSB Antenna
The Shakespeare 393 antenna can be used for various marine radio communication needs, such as:
SSB radio systems on fishing vessels.
Recreational boats and yachts.
Cruise ships and tourist vessels.
Workboats, support vessels, and marine fleets.
Long-range HF communication at sea.
Maritime radio communication systems using antenna tuners.
Emergency communication or inter-vessel coordination needs.
For a good installation, the antenna needs to be paired with a compatible SSB/HF radio, an antenna tuner, proper grounding or counterpoise system, quality RF cable, and a strong mount.
Installation Tips for the Shakespeare 393 Antenna
For the antenna to work optimally, installation must consider its position and supporting systems. Install the antenna in the highest possible area of the vessel, away from large metal structures, other antennas, or electronic devices that could cause interference.
Use an antenna tuner suitable for the 2–30 MHz frequency range. The tuner helps match the antenna's impedance with the radio on the frequency in use so transmission power can be delivered more effectively.
Additionally, ensure the vessel's grounding or counterpoise system is properly installed. In marine HF/SSB radio installations, grounding quality can greatly affect system efficiency and communication quality.
Perform periodic checks of the base, threads, cable connections, and the physical condition of the fiberglass. Although the Shakespeare 393 is designed to withstand the marine environment, routine maintenance is still necessary to keep the vessel's communication system always ready for use.
