How To Choose A Marine VHF Antenna – Buying Guide

Antenna’s Construction

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. One of the main things to consider along the search is the marine band antenna construction.

Usually, the most expensive designs will be ready to deliver the most amazing 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 options are made of metal in a fiberglass coating. Others are made of chrome-plated brass elements. The ones that come at their lowest quality are made of the plastic ferrule, which won’t do a great job or last as long.

Range Provided

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 the range of the signals sent. If you are using a sailboat antenna, the higher you can mount the device, the larger the range will be.

Device’s Gain

The gain is also called the dB rating and it 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 designs will have a stronger transmission but won’t be able to send the signal as far horizontally. Lower dB antennas will 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 when you are in need of a sailboat 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 will lose the ability to transmit horizontally. Lower dB ratings are broader, but the signal may not reach as far. Lower dB ratings also work better with transmitting signals along choppy water and rolling waves.

Antenna’s 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 VHF marine 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.

Device’s Design

Most marine band antennas are very 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 stouter and shorter, which makes them have a lower profile. Other designs include a digital antenna, which ensures that 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 fewer 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 right 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 devices are normally mounted high enough that the actual antenna itself does not need to be with an extremely tall design. Instead, the height of the sailboat would deliver what’s necessary to receive transmissions. Sailboat 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. The cable that is 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.

You should keep your cables as short as possible and use the largest diameter possible. Though, cables will add weight to your boat or vessel. With this in mind, 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. Not all marine VHF antennas will be sold with the same accessories. You can check the marine antennas before you purchase on the box, website, or brand information, which comes with your antenna. Brands should include whether a mounting kit is included with the purchase or needs to be purchased separately.

FAQs

What_Are_The_Benefits_Of_VHF_Antennas

Q: What are the benefits of a VHF antenna?

A: 

All radios need one to function. The best VHF marine antenna will help boost the signals of your radio, sending them further out, and with fewer disruptions. It will boost your radios signals, even over rough water, to ensure that your message is received. VHF antennas are used to keep you connected to the outside world when you are out on the water.

Q: How to mount a VHF antenna?

A: 

As stated, you should mount it at the highest point possible. However, you can attach it to a rail or use a flange mount to lock it in place on a vertical or horizontal location. Some can even be ratcheted onto a sloping surface. If you have a sailboat, the right place to mount the device would be on the mast. You should keep it away from other antennas and it should be kept a minimum of three feet from your VHF radio.

You will have to determine before you make a purchase whether a mounting kit is included with the purchase. If it is not, the same brand or manufacturer should have a mounting kit available for separate purchase.

Q: Is a VHF antenna necessary?

A: 

No, but it certainly helps. A marine radio should have a small one built into its design, but the distance of its antenna is significantly smaller than that of a VHF option. Installing one may not be necessary, but it should be. A marine radios antenna is not strong enough to transmit signals far distances and may not be reliable in choppy waves or rough weather.

It will boost your signal further out and connect you to the land and other vessels. It’s safer to have one and it can be extremely helpful in emergency situations.

It’s important that you understand that everything on your boat from the marine GPS systems to your radio and antenna, will function off of marine batteries, which should be installed in your boat. For extra protection, consider investing in marine battery boxes and marine battery chargers to keep you safe, even in emergencies.
