Detailed FAQ Section

How do I install the Shakespeare 5912 White VHF Antenna on a fiberglass boat?

Installing on fiberglass is straightforward. Use marine-grade screws or adhesive mounts to secure the dorsal antenna to a clean, dry surface. Ensure the included RG58 cable runs internally to the helm, avoiding power lines. Use a rubber grommet where the cable passes through the deck to prevent water leaks. Once installed, connect the PL-259 connector to your VHF radio. Always test the signal range after setup.

Is this antenna compatible with all VHF marine radios?

Yes. The Shakespeare 5912 White VHF Antenna comes with a standard PL-259 connector, compatible with virtually all fixed-mount VHF radios on the market. Whether you’re using brands like Icom, Standard Horizon, or Garmin, this antenna will integrate seamlessly.

What’s the effective communication range of this antenna?

With its 3dB gain, this antenna offers a communication range of approximately 5–10 miles, depending on your mounting height, radio power, and surrounding obstructions. It’s perfect for coastal and nearshore boating where reliable short-to-medium range communication is critical.

Can this antenna handle saltwater exposure and UV sunlight?

Absolutely. The heavy-duty ABS body is UV-resistant and corrosion-proof. It’s designed for long-term durability in harsh marine environments. Regular rinsing with fresh water is still recommended to extend its life, especially in saltwater-heavy conditions.

How does it compare to whip-style antennas?

While whip antennas typically offer higher gain and longer range, the Shakespeare 5912 White VHF Antenna excels in compactness, aesthetics, and durability. It’s also less prone to damage and ideal for high-speed boats where whip antennas can catch wind or snap. Choose whip-style for offshore, but go low-profile for coastal or clutter-free installations.
