Boaters who have more than one VHF or UHF radio will find a UHF VHF Antenna Splitter to be a very helpful piece of equipment. The primary objective of this kind of electronic equipment is to extend the coverage area of the signal that you are able to receive. Avoiding interference from other transmissions is another benefit gained by using a splitter. You are not permitted to place more than one antenna within a radius of two meters of each other.
-71,79,80,81,82,91,123,124In order to make use of both your VHF radio and your AIS transponder, you will need to have a separate antenna that is devoted to VHF and AIS communications. It is recommended that you install the antenna at a height that is significantly higher than your deck. This provides you with a clearer view of the signals.
It is recommended that you keep at least two meters of distance between the two antennas in order to achieve the best possible performance. It is significantly less likely that a single problem will render both the radio and the AIS inoperable.
Ensure that you obtain the MMSI number from the vessel license before beginning the installation of the VHF/AIS unit. You are going to require it for the DSC.
Approximately eight feet is the length of the conventional VHF masthead antenna. It has a vertical element and a downlead that is half the wavelength. This antenna has a higher gain than a shorter masthead antenna and is typically installed on the stern rail.
You need to make use of a high-quality cable with a marine grade and 50 ohms. It is important to check that the coax is not oxidized and that it is straight. It is imperative that you order the appropriate length dependant on the length of the antenna.
It is essential to perform a signal test in advance of fixing the antenna. Your receiver will experience problems as a result of a poor signal, which may also render the warranty null and void.
A plug for an AIS/vhf antenna splitter will be designated PL259, and it needs to be tightened in the clockwise direction. On the AIS/VHF cable, you should also make sure that the auxiliary VHF port, which is designated SPLITTER, is secure.
There are many different applications for antennas in today's world. Signal receiving and communication with both other ships and shore stations are two of them. It is essential to select the appropriate antenna for the particular vessel in question. Antennas for AIS and VHF radios can be installed on a ship to improve its ability to communicate with other vessels and to boost its level of operational safety.
Two antennas are typically required for VHF radios in order to successfully receive AIS signals. One for the Automatic Identification System (AIS), and one for ordinary marine band aerials. On the other hand, in the case that the VHF loses power, a single AIS/VHF antenna can be repurposed to function as an emergency uhf vhf antenna splitter.
When only one antenna for AIS and VHF is used, there is significantly less signal interference. Mounting the antenna at the highest point of the boat, away from any metal or other items that could potentially distort the signal, is the ideal placement for the antenna. The ideal distance, around three meters, should be maintained between the antenna for VHF radio transmission and the device being placed.
It is important to keep antennas clean. They should be cleaned with water and soap in order to eliminate any dirt or dust that may be present. Checking for physical damage and evaluating the level of performance are both components of a routine maintenance program.
An active splitter may be installed in an AIS/VHF antenna if so desired. These devices allow a connection to be made between the AIS device and the VHF radio while assuring that no data is lost in the process. Splitters have a lengthy history in the world of technology.
The reception of AIS signals can be improved by using an antenna that is both AIS- and VHF-capable. These broadcasts, such as digital terrestrial television, are broadcast using VHF frequencies; yet, the signal can be received over an extremely large geographical region.
Redundancy can also be achieved by employing the use of a dedicated AIS/VHF antenna. This is something that can be of great use for powerboats as well as sailboats with two masts. Mounting options for the AIS/VHF antenna include high up on the mast or on the stern rail.
Another option is to employ a dedicated AIS/VHF aerial as a stand-in for a standard emergency vhf radio antenna splitter. Additionally, it can utilize the VHF connection that is already installed on your boat. If you are in charge of a larger vessel that contains a significant number of Class A transponders, investing in a specialized AIS/VHF antenna may prove to be a prudent decision.
Utilizing an electrical splitter is yet another viable alternative. The use of splitters, which allow a VHF antenna to be shared with an AIS receiver, has been around for a number of years. On the other hand, they are not perfect.
A pre-amplifier is a better compromise than any of the other options. The AIS signal is extremely vulnerable to being distorted or corrupted by noise. A receiver's sensitivity can be maintained with the help of a pre-amplifier. In addition to that, it is a wonderful technique to extend the range of the radio.
A discriminator tap is typically included in the feature set of a radio of high quality. You should consider purchasing a discriminator tap if the radio you have does not already come equipped with one.
