The Best Marine VHF Antennas Of 2021

If you've purchased a VHF marine radio, you'll also need a Marine VHF antenna. The antenna is what transmits power and connects your radio to the rest of the world.

The marine VHF antenna is what sends the nautical radio signal from the radio. Why spend hard earned dollars on a quality fixed-mount VHF radio if you don't select a comparable antenna?

Experts agree that you should buy the best antenna you can afford.

A poor quality antenna misdirects your signals and shortens your range. A quality VHF antenna boosts your range. It also ensures the signal reaches its destination. Finally, it holds firm against all the jostling that high seas and high speeds can bring.

How to Choose a VHF Antenna for Your Vessel

When choosing a VHF antenna, you should consider the following options and weigh them against your needs.

Check the Antenna's dB Rating 

A VHF antenna's dB rating is also called the gain. The gain indicates how much the antenna can focus its energy to increase in transmitting power due.

A high dB rating means the antenna focuses energy perpendicular to its shaft and within a disk-shaped field. As a result, your radio signal appears stronger to nearby receiving stations.

High gain also reduces the amount of energy that transmitted above or below the VHF antenna. This can pose a problem if your boat is rolling or pitching in rough seas. A concentrated signal fades in and out during these conditions.

The height of an antenna increases along with the dB rating. But, the horizontal angle diminishes. For example, broad radiation from a low dB antenna enables a sailboat to heel over and still send a signal toward the horizon.

For this reason, a sailboat should have a 3dB antenna mounted to the top of the mast.

Compare Gains and Losses

A VHF antenna's gain in dB is offset by a loss in dB due to the coaxial cable inside the antenna. An increased gain of 3dB means a doubling of signal strength, but the actual watts that the antenna transmits aren't increased.

They are simply concentrated. This is why a radio with a 6dB antenna sounds like it has a larger transmitter compared to a radio with a 3dB antenna.

Now, a coaxial cable is efficient but loses some energy with every foot. For instance, an RG-58U coax loses 3dB for every 49 feet of run.

Think of it this way, if you have 49 feet run of cable, your radio will sound like it is only transmitting with 12.5 watts instead of 25 watts. If you run the same cable 98 feet, it will sound like a six-watt radio. 

You can put your antenna at the top of an 80-foot mast, and you'll have a good range, small coax and all. Though, your coax reduces the power.

It's recommended that you used the largest coax possible, especially for long runs. You'll have more weight aloft. That will increase heel and diminish sailing performance, so therein lies the compromise.

Pay Attention to the Antenna's Construction

VHF antennas are constructed with fiberglass or stainless steel. Shorter, stainless steel whip antennas work well for masthead-mounting.

They generate less windage and the wide radiation pattern that a heeling sailboat needs. Stainless steel antennas are rugged, so they are great for small powerboats.

Fiberglass tube antennas vary in quality. The best ones are those that are coated with polyurethane. Those last for about five to ten years.

These models will also have stainless steel ferrules as well as copper and brass parts to ensure good range efficiency. Cheaper antennas use nylon ferrules, which are weaker and don't hold up nearly as well.

Below are some reviews of the best VHF antennas for 2021. These are the models that consumers have rated the highest.
