Today, wireless technology is not only important for terrestrial life but also for marine applications. Have you ever wondered how you can enjoy wireless technology even when you're in the middle of the ocean? There could be two antennas behind it, one marine antenna designed for sea communication. And another shipboard antenna fixed to the vessel for onboard communication and control. The question now is, are these two antennas the same? If not, what are the differences between them? This post will focus on this aspect. Here, we will explore the key difference between marine antennas and shipboard antennas. Let’s get started!

What is a Marine Antenna?

A marine antenna is a special kind of antenna that is mainly designed for ships, boats, and other marine vessels. The purpose of this antenna is to let you connect to the wireless technology. Just remember your last movie, where characters were using smartphones and even telephones to send and receive calls when they were on the boat. This is what marine antennas can enable users to do when they are on their marine travels.

With the help of a marine antenna, you can send and receive signals over water. This antenna is similar to any other antenna that is used in terrestrial wireless connectivity. But the only difference is that marine antennas are designed to perform well even in the harsh weather and atmospheric conditions of the ocean.

Introduction to Marine Antenna and Shipboard Antenna

What is a Shipboard Antenna?

A shipboard antenna is not a separate wireless device from a marine antenna. It is just a part of the broader category of marine antennas. Let’s not cause any confusion! A marine antenna is a general term used in any marine environment. While the shipboard antenna specifically refers to antennas that are used on large ships for wireless communications. It is mounted at high points of the ship for better signal strength. Its design is durable enough to handle harsh marine conditions like saltwater, wind, and vibration.

Key Difference between Marine Antenna and Shipboard Antenna

Let’s talk about the difference between a marine antenna and a shipboard antenna:

Design

A shipboard antenna is indeed part of a marine antenna. But the obvious difference that you can see between the vast category of marine antennas and a dedicated shipboard antenna is their design. Yes, most marine antennas are simpler and smaller in size. With this unique advantage, they are easy to install and take up less space in the marine vehicles. That gives extra space in the boat for more and other stuff.

On the other hand, when you compare shipboard antennas with other UHF marine antennas. One clear sign you can find is that shipboard antennas are larger and more powerful. They are built to handle harsh ocean environments and continuous operation. Their large size ensures a high gain. And it maintains better communication in large ships and passenger boats.

Function

Most marine antennas are designed to provide wireless communication in small boats or for coastal use. If you ever travel on such a marine vehicle. You may find a VHF marine antenna to get access to simple communication, navigation, and weather updates. Their support helps users to get access to basic ship-to-ship communication. However, they are not made for complex data transmission.

On the other hand, a shipboard antenna is an advanced type of marine antenna. The large ships that travel from one city to another or country to another are often equipped with this wireless solution. And ensure offering functions like radar, GPS and satellite links for long-distance and mission-critical operations. The reason why naval shipboard antenna provides advantageous features and functionality is that ships travel long distances in open seas. Their supporting facilities help ensure continuous communication for both passengers and the ship crew.

Frequency Range

Marine antennas mainly work on limited VHF or UHF frequencies. And that is not a negative aspect, but the very operations that happen in those marine vehicles are limited to that. These bands well enough to perform the job and provide short-range communication over water. For example, a VHF marine antenna is used for ship-to-ship or ship-to-shore radio. While a UHF marine antenna supports onboard systems and radar. These work fine even in the harsh ocean environment.

While shipboard antennas operate across multiple frequency bands for radio, radar, and satellite systems. It works with multiple bands, such as VHF, UHF, HF (high frequency), MF (medium frequency), L-band, and C-band, depending on the system being used. That is the point where ship antennas outperform other marine antennas. It gives you flexibility and versatility that enable long-distance global communication via satellite and radio. The crew members on the large ship can get continuous monitoring and navigation across international waters.

Usage

This is the last but not least point that will clear your doubt. Marine antennas are used on many marine vessels, including small boats, yachts, fishing boats, coast guard patrol boats, and rescue vessels. They are helpful to establish short-range communication, GPS navigation, weather alerts, and safety messages between nearby ships or coastal stations. The primary use of these ship antennas is to maintain VHF and UHF radios for coastal operations.

Talking about the Shipboard antenna, it is used in professional and defense communication systems. It is installed on cargo ships, naval ships, cruise ships, oil tankers, and research vessels. Working with multiple frequency bands, this ship antenna helps users to ensure safe navigation, ship control, and communication over long ocean routes. During long-distance travelling, it is the solution that avoids obstructions and shows the right path.

Bottom Line

We drove deeply and explored the difference between marine and shipboard antennas. We understood that both of them are closely related but have many differences in their function, range, and application. On the one hand, “marine antennas” refers to all antennas used for marine wireless communication. On the other hand, shipboard antennas are a part of marine antennas but are used only for large vehicles like cargo ships, naval ships, and cruise ships.

Both of the antennas are very important in making wireless communication and performing various operations in marine environments. With them, you may not get access to the internet and mobile calls. And ships may not receive reliable communication support through regular routers while at sea. The advanced functionality and technology of both devices support modern maritime operations and safety. If you want to purchase any of the antennas, connecting with the best marine antenna manufacturer is the best approach.
