Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB Review

Is the Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB Worth It? Let’s Find Out

When you’re out on the water, reliable communication isn’t just a convenience; it’s a critical safety factor. For years, I’ve relied on various communication tools across a wide spectrum of environments, but marine VHF has always demanded a certain robustness. My search for an upgrade to my boat’s comms system led me to the Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB. This is a serious piece of kit, designed for serious marine applications, promising excellent signal clarity and range. My existing antenna, a much shorter, older model, had started showing its age, exhibiting a noticeable degradation in performance during less-than-ideal weather. The need for better reception, especially for receiving weather alerts and maintaining contact with shore or other vessels, became paramount.

First impressions of this Shakespeare unit were positive. The hi-gloss fiberglass construction feels substantial, and the overall build quality speaks to its marine-grade intentions. It possesses an aura of durability that immediately inspires confidence, a crucial trait when dealing with the harsh realities of the sea. I had considered a couple of other antenna brands, particularly those offering more compact, disguised designs, but their stated gain figures and build materials simply didn’t stack up. The thought of a more powerful, dependable communication link on board brought a sense of practical relief.


Real-World Testing: Putting Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB to the Test

First Use Experience

My testing ground for this antenna was my 26-foot sailboat, primarily used for coastal cruising and day trips along the Eastern Seaboard. The installation was straightforward; I replaced the old antenna at the top of the mast. The 18ft length meant a significant increase in height, which is a fundamental factor for VHF range. I spent a full weekend out on the water, covering about 50 nautical miles, testing its performance in varying conditions.

During this initial trial, the difference was immediately apparent. Even with a moderate chop and a brisk 15-knot breeze, my transmissions were reportedly clearer than ever. Receiving distant weather broadcasts was also remarkably improved; stations that were previously a struggle to pick up were now coming in with a strong, clear signal. The 9dB gain certainly lives up to its promise, providing that much-needed boost. There were no immediate issues or surprises, just a consistent, solid performance that felt robust.

Extended Use & Reliability

Over the subsequent few months, this Shakespeare VHF antenna has become a permanent fixture on my vessel. It has weathered several significant storms, with winds exceeding 40 knots and heavy seas, without any adverse effects. The antenna remained perfectly stable, and communication channels stayed open.

In terms of durability, there are no signs of degradation. The fiberglass radome still boasts its original shine, and the stainless steel ferrule shows no corrosion, even after repeated exposure to saltwater spray and sunlight. Maintenance has been minimal; a simple rinse with fresh water after a long outing is all that’s needed. Compared to previous, less robust antennas I’ve used, this unit is a world apart; budget options often start to flex or degrade in their elements within a year, but this Phase III model feels built to last.

Breaking Down the Features of Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB

Specifications

The Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB is a high-performance antenna designed to maximize VHF radio communication range and clarity. Its substantial 18ft length is a key component in achieving superior signal propagation by providing increased height above the waterline and surrounding obstacles. The antenna boasts a 9dB gain, a significant figure that indicates its ability to focus radio energy in a specific direction, leading to stronger outgoing transmissions and more sensitive reception.

It operates on a standard 50 ohm impedance, ensuring compatibility with most marine VHF radios and coaxial cables. The construction features a hi-gloss fiberglass radome, which is both durable and aesthetically pleasing, resisting UV degradation and saltwater corrosion. Internally, it utilizes silver plated outer and copper inner conductors, materials chosen for their excellent conductivity, which minimizes signal loss. The mounting hardware includes a robust stainless steel ferrule, offering strength and corrosion resistance essential for a marine environment. A notable feature is the Type SO-239 connector integrated within the mounting sleeve, simplifying installation and removal for storage. This antenna is designed for dedicated VHF marine band communication.

Performance & Functionality

The primary job of a VHF antenna is to transmit and receive radio signals effectively, and this Shakespeare unit excels at it. The 9dB gain provides a noticeable improvement in both outgoing signal strength and incoming reception sensitivity. On longer voyages, I found that my radio’s effective range was extended, allowing for clearer communication with distant vessels and shore stations.

Its main strength lies in its ability to maintain signal integrity even in challenging conditions. The increased height from the 18ft length means it clears more obstructions and benefits from the curvature of the Earth more effectively. A slight weakness, though not inherent to the antenna itself, is that its length can make it more susceptible to windage on smaller vessels; careful mounting and consideration of mast flexibility are important. It consistently meets and often exceeds expectations for a high-gain marine antenna, especially considering its price point and build quality.

Design & Ergonomics

The design of the Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB is focused on ruggedness and performance. The hi-gloss fiberglass radome feels solid to the touch, with a smooth finish that repels water and dirt. The stainless steel ferrule at the base is substantial and provides a secure mounting point.

Ergonomically, its primary function isn’t about handheld comfort, but about efficient installation and stable mounting. The integrated Type SO-239 connector in the mounting sleeve is a thoughtful touch, allowing for quick connection and disconnection, which is useful for storage or transport. The overall feel is one of robust engineering, designed to withstand the constant vibration and environmental stresses of marine life.

Durability & Maintenance

This antenna is built for longevity in the harsh marine environment. Shakespeare rates it for the elements, and my extended use confirms this. The hi-gloss fiberglass radome is highly resistant to UV damage and fading, and the stainless steel ferrule is impervious to rust and corrosion from saltwater.

Maintenance is exceptionally simple; a quick rinse with fresh water after use is sufficient to keep it in top condition. There are no intricate parts to clean or maintain, making it a low-hassle component for any boater. Potential failure points are minimal, given the robust materials and straightforward design, likely making this a long-lasting installation on any vessel.

Accessories and Customization Options

The Shakespeare Phase III Marine VHF Antenna, 18ft, 9dB itself is the primary component, and importantly, no cable is included with the purchase. This means you will need to source appropriate 50 ohm coaxial cable (like RG-8X or RG-213) and connectors separately, which is a crucial point for buyers to note. Shakespeare does suggest specific mounting kits, such as their Style 409-R or 410-R mounting kits, which are designed to work seamlessly with this antenna’s ferrule.

While there isn’t much in the way of “customization” for the antenna itself, the selection of the correct cable and mounting hardware are essential for optimal performance and installation. The Type SO-239 connector in the base means you’ll need a cable with a PL-259 connector to mate with it directly.
