What kind of antenna do I need for a marine radio?
If it’s a lot, the receiving radio may experience a fading signal. For a powerboat under 24 feet or a sailboat, a 3 dB antenna is recommended. Usually a 6 dB antenna is recommended for boats over 24 feet and a 9 dB antenna is recommended for boats over 32 feet.
What are the long antennas on boats for?
The broad radiation pattern from a low dB antenna allows a sailboat to heel over and still send signals toward the horizon. Sailboats should use a 3dB antenna mounted at the top of the mast whenever possible.
How tall should my VHF antenna be?
“As a general rule, antenna height should be less than half the length of the boat,” Catoe says. Higher-dB antennas generate greater effective radiated power, and that can translate into greater range.
Can VHF antenna be used for FM?
Marine VHF antennas can be used to receive two-way communications and weather band signals alike. Also, unlike AM or UHF, VHF can receive VHF TV stations and FM radio as well.
Do marine VHF antennas wear out?
The antennas do not actually ever “go bad” however just like everything they are susceptible to water damage. If yours is sealed and has no signs of corrosion it will be fine. All that is inside of them is a wire of the proper wave length, keep it dry and it will last forever.
Does a VHF antenna need to be vertical?
Your VHF antenna attached to the AIS device needs to be as high as possible and as far away as possible from other vertical metal objects. Vertical metal objects include other vertical antennas, sailboat masts, radar masts, stays, bimini frames and any other lengths of metal parallel to the antenna.
Does a VHF antenna need to be grounded?
VHF antennas that come with an integrated ground plane do not need to be grounded. VHF antennas that do not have an integrated ground plane must be grounded, and their instruction manual will tell you how. Either way, you need to consult the installation instructions for the antenna that you buy.
Does bigger antenna mean better reception?
It’s about gain. A bigger antenna, properly designed, will always have more gain than a smaller one. And it will be the best kind of gain, much better than using a small antenna and simply overamplifying it, because a small antenna just won’t pull in truly weak signals like this gigantic one will.
Which is the best VHF antenna for a marine radio?

What kind of antenna do I need for a boat?

Do you need an antenna for a two way radio?
Vehicle/Mobile Two Way Radio Antennas Mobile two way radios install in a vehicle and always require the addition of an external antenna. Because there are so many options regarding mounting styles and antenna sizes, it is extremely rare to see an antenna included with a mobile radio. Most mobile radios require a PL259, or UHF, style connector.
