What Is An AIS Antenna?

What Is An AIS Antenna?

For example, AMEC states in its CAMINO-108 manual, “… the VHF antenna should be placed as high as possible and at least 5 meters away from any constructions made of conductive materials.” Vesper recommends, “Mount the antenna as high as possible (at least 2-3 meters (6-10 ft) above the water surface) and as far as

What do you need for AIS?

AIS works via a combination of GPS, VHF radio, and an AIS transponder. The transponder broadcasts a ship’s information, such as speed and heading (information gathered by GPS, of course), the ship’s name, port of origin, size and draft, and more, over VHF frequencies 161.975 megahertz and 162.025 MHz.

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.

Does a VHF marine radio need an antenna?

VHF antennas are a crucial part of your VHF installation. Understanding how they work and how to select the correct antenna can greatly improve your ability to communicate with other boaters and shore stations.

What channel should I have my marine radio on?

Federal Communications Commission regulations require boaters having VHF radios to maintain a watch on either channel 9 or channel 16, whenever the radio is turned on and not communicating with another station. All non-emergency traffic should be communicated on another channel (not channels 9 or 16).

Is AIS worth the money?

However, for boats venturing further offshore and likely to meet reduced visibility and other inclement weather, as well as engaging in more night sailing, an AIS receiver is clearly a valuable and relatively inexpensive aid to help avoid potential collision situations.

Is AIS better than radar?

AIS is more accurate than radar since it is continuously fed with data from reliable sensors. Radar can have very poor accuracy when tracking a target. AIS maintains its accuracy and gives a prompt indication of changes in heading, and will give the rate of turn if it is available from the target.

What is the difference between AIS Class A and B?

The main difference between Class A and Class B units is the power output, Class B transmits at 2W, giving a range of between 8-10 miles, whilst Class A transmits at 12.5W giving a much larger range.

What boats are required to have AIS?

AIS Rule Change for US Waters

The following vessels are required to install and use a Class A AIS transponder: All commercial vessels of 65 feet or more in length (except as defined below) Towing vessels of 26 feet or more in length and more than 600 horsepower. Vessels certificated to carry more than 150 passengers.

Do VHF antennas go bad?

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.

How long does a VHF antenna last?

These antennas use stainless steel ferrules, combined with brass and copper elements, to provide maximum efficiency and range. They typically last for five to ten years. Antenna height, more than anything else, determines the distance you will be able to transmit radio signals.

What is the maximum range of AIS?

The AIS signals have a horizontal range of about 40 nautical miles (74 km), meaning that AIS traffic information is only available around coastal zones or in a ship-to-ship zone. AIS communication takes place using two VHF frequencies, 161.975 MHz and 162.025 MHz, using a bandwidth of 25 kHz.

Is it possible to connect GPS with the AIS?

Our very popular AMEC CAMINO-101 Class B AIS transponder can now either use its internal GPS system coupled with the AMEC external antenna or it now supports using an external GPS device connected through the inbound NMEA port. … Keep in mind that the internal GPS source has higher priority.

What is the purpose of AIS?

The automatic identification system, or AIS, transmits a ship’s position so that other ships are aware of its position. The International Maritime Organization and other management bodies require large ships, including many commercial fishing vessels, to broadcast their position with AIS in order to avoid collisions.

When can AIS be switch off?

According to IMO guidelines provided by Resolution A. 917(22), AIS should always be in operation when ships are underway or at anchor. Only if the master believes that the continual operation of AIS might compromise the safety or security of the ship, the AIS may be switched off.

What is the advantage of AIS over radar during bad weather?

The system is fully automated with absolutely no human intervention. Unlike Radar, It is not affected by rains or Sea. Its propagation is better than that of radar, due to the longer wavelength. It’s possible to “see” around bends and behind islands if the land masses are not too high.

Do I really need radar on my boat?

A marine radar device acts as a major navigation aid for boaters. It helps in detecting boats, birds, landmasses, and weather systems – even if the visibility is less than usual.

What is the best AIS transponder?

What is the difference between AIS transponder and transceiver?

There is a difference between AIS receivers, with which you can see information about surrounding boats but cannot transmit your own, and AIS transceivers, also called AIS transponders. AIS transponders receive the AIS data of the surrounding boats and at the same time transmit the data of their own boat.

How do I change my AIS information?

You are not allowed to change the ais name. It is changed to the mmsi which cannot be changed on the unit. You have two options, have the previous owner transfer the mmsi to your name or remove the unit and send it back to manufacture. They can reset the unit and you can reprogram the unit to a new mmsi.

Do police use UHF or VHF?

Police radios operate in a 700/800 MHz UHF band.

Why is it illegal to use a marine radio on land?

Marine radios can function on land; however, because marine radios are used by vessels in situations of distress, navigational issues, personal communication, and business needs, it is not legal for a person to use a marine radio on land without an approved coast station license.

What is the emergency channel on marine radio?

However, channel 16 on your VHF radio is probably the most important. Channel 16 is designated as the national distress, safety and calling frequency. All vessels should monitor this channel while underway.

For example, AMEC states in its CAMINO-108 manual, “… the VHF antenna should be placed as high as possible and at least 5 meters away from any constructions made of conductive materials.” Vesper recommends, “Mount the antenna as high as possible (at least 2-3 meters (6-10 ft) above the water surface) and as far as
