When it comes to your safety, you want the best. You should spend the time to find the best VHF antenna for your needs and ensure that it has high quality features to deliver a strong and reliable performance. Marine speakers, radios, and antennas are essential to having a safe and fun time on the water.

Here, we have some key features in marine VHF radio antenna designs that can determine a high quality antenna from a low quality antenna. By reviewing these features, you can also determine which marine band antenna would be suit your needs.

Construction

You will want to find an antenna that has a durable construction to ensure it will be long lasting and function properly. The more expensive vhf antenna marine designs will have the best performance. You should try to invest in a high quality construction because they will be made of quality materials and will last longer.

Some of the best vhf antennas are made of metal in a fiberglass coating. Others are made of chrome-plated brass elements. The lowest quality would be made of plastic ferrule, which won’t do as great of a job or last as long.

Range

The range of the antenna determines how far away the signals from your radio can be sent. The best vhf boat antenna will ensure that your signals are being sent far away without complications. All marine band antennas should tell you their range, which can help you determine if it will suit your needs. The way that you mount your antenna can also affect how far of a range it is able to send signals. If you are using a sailboat vhf antenna, the higher you can mount the device, the larger the range will be.

Gain

The gain is also called the dB rating and is an indication of how the antenna focuses its energy. The type of boat or vessel that you have will also determine your gain and the attention you should consider. Higher rated vhf antenna marine designs will have a stronger transmission but won’t be able to send the signal as far horizontally. Lower dB antennas have a broader pattern of radiation, which may get your signal to more places and be helpful in certain situations. Lower dB is mostly recommended for use as a sailboat vhf antenna.

Decibel Rating

This is in correlation with the gain. The decibel rating will determine how far out your signals can be sent. Higher dB ratings tend to have a stronger transmission, but they lose the ability to transmit horizontally. Lower dB ratings are broader, but they signal may not reach as far. Lower dB ratings also work better with transmitting signals along choppy water and rolling waves.

Durability

Any vhf marine radio antenna should be extremely durable. You want a design that is durable because it will last for a longer amount of time, deliver a stronger and more reliable performance, and be made of materials that can withstand the harsh ocean elements. The best marine vhf antenna will be durable enough to withstand the salt, water, and sun. It should still function properly without complications even after a few years of use.

Design

Most marine band antennas are compact in design. The main difference between designs and brands seem to be the height of the antenna. Some antenna designs are rather tall and skinny, much like you would expect an antenna to be. Other designs are more stout and shorter, which makes them have a lower profile. Other designs are a digital VHF antenna, which ensures all signals are correctly broadcasted.

Height and Range

The height of the antenna will determine the range of sound that your antenna can pick up. A higher antenna will be able to receive an original transmission better because it will rest above a lot of obstacles. This means there are less obstacles to get in the way of the signal as it reaches your antenna.

All antennas should be mounted at the highest possible location on your boat or vessel, which can help ensure that it receives the best signal. The longer the design of your antenna is and the higher it is mounted, the clearer the transmission will be.

However, taller boats like a sailboat vhf antenna are normally mounted high enough that the actual antenna itself does not need to be an extremely tall design. Instead, the height of the sailboat would deliver what’s necessary to receive transmissions. Sailboat vhf antennas can be shorter in design, if they are mounted at the proper height. On the other hand, a short and compact boat would need an antenna that is tall in its design.

Cable Loss

Cable loss dictates that for every foot of cable used, the signal strength is lost. Cable that are shorter in length, about 10-20 feet, should not have any problems. However, cables that are 100 feet on a small boat, like a sailboat, can cause problems. In this situation you could lose up to 80% of your signal.

The best you can do is keep your cables as short as possible and use the largest diameter possible. Though, cables will add weight to your boat or vessel, so you should be sure that you’ve accounted for the weight of the vhf boat antenna system and its cables in correlation to your boat and its size.

Mount Included

This will be dependent on the brand of your VHF antenna. Not all marine VHF antennas will be sold with the same accessories. You can check before you purchase on the box, website, or brand information, what comes with your VHF antenna. Brands should include whether a mounting kit is included with the purchase or needs to be purchased separately.
