How to choose an omnidirectional TV antenna on a ship

How to choose and buy a well-known brand antenna for receiving terrestrial television and radio signals in the sea
How to choose an omnidirectional TV antenna on a ship
The high-quality reception of terrestrial analog and digital signals in the open sea in order to provide ship communications, television and other types of communications with the outside world makes the highest demands on the appropriate receiving equipment, in particular marine omnidirectional antennas. The task of equipping movable objects with television equipment is of great importance in connection with the development of shipping, including small ones, increasing the requirements for the comfort of yachts, boats and other swimming facilities, improving the working conditions of the crews of larger vessels.

Omnidirectional antennas
Omni-directional TV antennas are mounted on ship masts and have an almost round radiation pattern, since for a moving object, and even more so at sea, there is no dedicated direction for receiving terrestrial television signals. The gain of such an antenna is approximately the same in the horizontal plane in all directions, allowing you to maintain high-quality reception regardless of the movement of the vessel and without the need for constant reorientation of the omnidirectional antenna.

Marine Omni Directional Antennas
The omnidirectional antennas used on ships can also be called, for example, marine TV / AM / FM antennas or marine VHF antennas, indicating, on the one hand, that they correspond to certain frequency ranges, and on the other, belonging to the family of omnidirectional antennas . This family also includes 3G / 4G antennas designed to equip coastal vessels with Internet connection, as well as Wi-Fi antennas for organizing Internet coverage of the entire vessel. All of these antennas are united by a circular radiation pattern, otherwise their quality is determined by the engineering idea of ​​the creators.

Broadband marine omnidirectional antennas are the most high-tech TV antennas to receive a wide range of terrestrial television signals with a good level of quality. TV antennas used on ships in the sea are exposed to salt water, which is an extremely aggressive environment, wind, ship pitching and even lightning strikes. Therefore, ship TV antennas must have exceptional strength, waterproof and lightning protection characteristics.

Marinek company offers omnidirectional TV antennas from several leading world manufacturers, in particular Glomex, Shakespeare and Scout, on the pages of the catalog of its online store. Consider the most prominent representatives of the family of ship antennas and highlight on their example some features and functions.

Omnidirectional Antennas Glomex ALTAIR V9126
The omnidirectional 10-inch antenna Glomex V9126 Altair is one of the most famous and popular ship TV antennas on the market. The robust construction, ergonomic design and impressive features have made it attractive and recognizable in many countries around the world. The antenna is suitable for accommodation on ships of many types – from motor boats to large yachts and commercial ships. A feature of the Glomex V9126 Altair is the presence of an amplifier with By-Pass function, that is, this antenna is active with the ability to work in passive mode. Active antennas allow you to convert the incoming signal to achieve its optimal quality, at the same time, in areas of an already sufficient level of the incoming signal, the amplifier can spoil the result with its own noises, for which the so-called By-Pass function is provided in the antenna system design, allowing to use the received signal without amplification directly. The installation of such an antenna, as well as any other, is carried out at the top of the mast with the condition that it will be in different planes with the radar, because otherwise they will interfere with each other to work normally. When installing the antenna on the mast, it is imperative to use the side bracket and cable with double shielding RG6 DSS, which has the lowest signal attenuation. In the presence of the so-called splitter (frequency splitter), not only a TV, but also a radio receiver can be connected to such an antenna. By adjusting the signal level with the help of an amplifier, using such an antenna you can achieve the best sound and image quality. The Glomex V9126 omnidirectional antenna amplifier is installed separately in a well-ventilated area with easy access to adjustments. When installing the TV antenna itself, it is necessary to check the absence of nearby metal surfaces and other obstacles, which is why the mast is the best place to install omnidirectional antennas.

Shakespeare HDTV MAR14
The Shakespeare HDTV Mar14 marine omnidirectional antenna has a diameter of 14 inches and, due to its size and design, provides excellent reception quality. TV antennas of this family, called Anywhere, have earned recognition among users.
