Welcome to the page of our HiNelson e-commerce dedicated entirely to nautical antennas: here you will be able to find the best equipment for boats of all sizes and types, sail and motor. Leading the way, in this special category, are undoubtedly Glomex antennas, which not by chance have been the preferred choice of the most important boatyards internationally for years now.
To say'Glomex antennas', therefore, is in itself a guarantee, and this the sea wolves know very well. But this is not to say that choosing the perfectGlomex antenna for your boat is child's play: as you can see on this same page, the offer is in fact wide and heterogeneous, and therefore it is worthwhile to properly inform yourself about the characteristics of each individual nautical antenna, so that you can then choose the most suitable one according to your needs.
And it is precisely for this reason that we wanted to make this little guide: in fact, here you will find all the indispensable information you need to choose your Glomex TV antenna - and if that's not enough, of course, you can count on our assistance: just click on the appropriate button at the bottom right to leave a message to which we will respond as soon as possible!
The Ravenna-based Glomex logo doesn't mince words: in fact, the slogan is blunt, confident and proud, declaring that their products are 'The best in marine antennas.' After all, Glomex antennas were not born yesterday. No sir: the Ravenna-based company has been in business since 1984, founded by Piero Baldessari. The brand, in short, is well past thirty years of age, and the experience it has gained is accompanied by a constant quest for innovation, strengthened by the iron will of Pietro - who, as he likes to emphasize, was trained 'at the university of the dock,' working for years in shipyards.
Right from the start, the company's mission has been to produce quality nautical antennas so that boaters can connect seamlessly to access all types of maritime telecommunications. And you know, those who work well and invest wisely in research and human resources, always ensuring a high level of efficiency, are bound to expand their reach year by year. Today, Glomex TV antennas are appreciated everywhere, enjoying stable relationships with manufacturers and distributors all over the world.
Reliability, high technology, sophisticated design, efficiency, durability, wide choice, there are so many advantages of buying Glomex antennas. However, if one wanted to mention an element that even more than the others can outperform the competition when it comes to nautical antennas, that is certainly the lifetime warranty on all products: in fact, no one else in this sector comes close to offering such a guarantee.
And why does the Ravenna-based company Glomex succeed in doing this? Why does a Glomex TV antenna enjoy a lifetime warranty, while its colleagues from other brands cannot offer anything remotely comparable? It is quickly said. This is possible because behind every Glomex antenna there is a meticulous and painstaking selection of raw materials to be used in making the devices. There is continuous research to arrive at the best nautical antennas, and there are incessant checks carried out daily to be sure that we always give the best, in full compliance with international standards.
There is certainly no shortage of Glomex distributors, in Italy as well as around the world. But why set out in search of physical stores when you can conveniently buy your Glomex TV antenna online? Just two clicks and the deal is done, with the possibility of taking advantage of generous discounts. And that's not all, as the company is also famous for the careful packaging of each and every product, which is shipped and delivered in special packaging, so as to eliminate any worries in the customer. Given the quality of the product, in fact, it would be absurd to jeopardize its integrity through careless shipping!
When it comes to Glomex TV antennas, one is essentially faced with a choice between three different technologies: there are omnidirectional antennas, directional antennas, and satellite antennas. Taking for granted the fact that everyone now knows what differentiates satellite antennas from other devices, we want to emphasize the difference-unknown to most- between omnidirectional antennas and directional antennas.
When we talk about omnidirectional antennas we refer to devices that receive from all directions, and therefore 360 degrees. It is a different matter, however, with regard to directional antennas, which, on the other hand, need to be carefully oriented, as they receive only in a certain direction, for an angle of only 60 degrees
Is it better to have an omnidirectional antenna or a directional antenna? Well, those who understand telecommunications know very well that, receiving from any direction, an omnidirectional antenna cannot have much gain. A directive antenna, on the other hand, is limited to a small angle of 60 degrees, and for this reason turns out to be three times more effective than its full-range counterparts.
To get the maximum signal and thus enjoy an optimal signal, the directive antenna can be oriented easily with the simple use of the remote control.
Speaking of Glomex antennas, we talked about gain, one of the main parameters to consider when you want to purchase a receiving device. Starting from the basic assumption that an 'antenna' can be defined as any device capable of picking up electromagnetic waves radiated into space and then converting them into an electrical signal, the gain of an antenna, expressed in dB or dBi, is a value that gives us a rather clear idea about the actual receiving - and transmitting - capacity of such a device.
However, it would be simplistic to think that an antenna with a higher gain is automatically the best antenna overall. Things, in fact, are not like that: without going to look at overly difficult mathematical formulas, we can simply recall that the gain of an antenna is the result of the ratio of power density radiated in a precise direction to the power density that could be generated of the same direction by an isotropic radiator.
However, it should be emphasized that the isotropic radiator, also called an isotropic antenna or elementary diipole, actually corresponds to a theoretical mathematical model. In short, it does not exist in reality, and can never be built, since it is a device that radiates uniformly, with the same intensity, in any direction.
Based on these assumptions, we can say with full knowledge that an antenna with higher gain is not always preferable. On the contrary, one could in fact have a 12 dBi gain omnidirectional antenna that, while radiating better than an 8dBi antenna in the plane perpendicular to its longitudinal axis, ends up radiating much less in the other directions. Therefore, we are not talking about a 'better' or 'worse' value in absolute terms, but rather a figure that must be put in relation to the specific use.
The success of Glomex antennas can also be attributed to the quality of the materials used to manufacture the devices. In fact, all nautical antennas are made of the special plastic material ASA, or acryloyl-nitrile-styrene-acrylate: for those who understand thermoplastic materials, suffice it to say that it is an amorphous polymer from the styrenic family. Those who want to buy Glomex antennas, however, do not need theoretical definitions. In fact, what is important is to know that such a material has excellent hardness and good mechanical properties. But that is not all there is to it. Unlike many other plastic materials, the ASA used in the construction of these nautical antennas is not subject to the typical deterioration processes caused by weathering and the marine environment.
In short, Glomex antennas are resistant to the annoying yellowing that is characteristic of many other lower-quality devices. It should come as no surprise, then, that ASA is replacing high-impact shockproof polystyrene (i.e., HIPS) in most outdoor applications, precisely because of its greater resistance, especially to the elements. Once placed on one's boat, therefore, Glomex TV antennas keep their beautiful glossy white color intact, not compromising the aesthetics of the boat.
Once you have purchased the Glomex antenna best suited to your needs, all you have to do is wait for the package to arrive, directly to your home. But what will accompany the antenna? What will be in the package? In addition to the actual antenna, a 20-meter coaxial cable-which is reduced to 10 meters in the case of certain models of Glomex omnidirectional TV antennas, such as the Avior VT3000-is included in the price, as well as any tools needed for installing the connectors that are delivered.
In addition to classic directional and omnidirectional TV antennas, Glomex offers a wide range of satellite TV antennas. The offer was later enriched with the introduction of second-generation Digital Video Broadcasting-often abbreviated to DVB-S2-which gives boaters the opportunity to receive a highly satisfactory TV signal, so they can enjoy viewing Full HD and 4K channels even at sea.
A peculiar objective of Glomex satellite antennas is the elimination of noise, which, coupled with innovative high-performance parabolic disks, ensures total and enviable silence, annihilating disturbances related to the progressive increase of satellites in orbit.
Glomex satellite TV antennas, as anticipated, have taken a leap forward in the universe of nautical telecommunications, moving to DVB-S2. But what specifically are we talking about? The simple abbreviation DVB-S refers to any satellite television transmission. We are therefore talking about transponders having an average capacity of about 40 MBps: with these values it is usually possible to transmit on the same frequency no more than 10 standard channels or, in the case of HD transmission, no more than 5 channels. The more channels transmitted on the same transponder, the lower the quality of transmission.
Thus, one can understand the reasons for the development of DVB-S2, which precisely goes to widen the bandwidth of transponders: thus, we are no longer talking about 40 MBps, but instead about 65 MBps. With these figures it is possible to achieve transmission on the same frequency of up to 10 HD channels, an achievement simply unthinkable at the previous stage.
There are no absolute rules for installing these devices on one's boat, as much as there is one general rule of thumb: Glomex TV antennas should be installed high up, away from any possible signal obstruction.
In the case of sailboats, the best place to install a Glomex antenna is undoubtedly the masthead, using the appropriate mount.
Absolutely: this is why it is necessary to install the antenna on a different level than the radar, so as to eliminate any mutual interference.
Absolutely not: in fact, inside the package of the Glomex nautical antenna you will also find a special tool, through which you can easily screw the connector.
This depends on the splitter used: connecting to a V9147 splitter the maximum number of devices is two, while with a 50022 splitter you can get up to 6 TV sets.
There are two possibilities: you can extend the present cable with an additional cable, connecting the two through an F connector. However, in this way you will lose gain, which will decrease for each additional connection. The second - more effective - method, on the other hand, is to replace the previous coaxial cable with a longer one: doing so will not compromise signal quality.
The place to install the amplifier should be located in a dry, ventilated place that allows easy access to the gain knob (which should be adjusted to eliminate any factors that may adversely affect signal reception).
