Towers for telecommunication antennas

Directivity is a quantity that is expressed in terms of the Isotropic antenna that radiates with the same total power. This antenna is used because it is an antenna that radiates in all directions with the same energy.

Although it is not physically possible to generate this antenna, it is a good theoretical reference for this type of comparisons. The directivity (D) is then defined as the ratio between the maximum radiation intensity of the antenna with respect to an isotropic antenna of the same total power.

It is a different way of expressing the mismatch, it is a ratio that expresses the ratio between the power reflected by the antenna and the power delivered by the transmission line with which it was fed. Its units are dB and it is related to the Standing Wave Ratio (SWR) by the following equation.

What is a lattice tower?

An electrical tower or electrical support (sometimes referred to as a turret) is a high-rise structure, usually constructed of steel latticework, whose primary function is to support electrical power transmission lines.

How does a radio antenna work?

Antennas are devices that allow transforming the electromagnetic energy that goes through a conductor, waveguide or other device that carries a radio frequency signal, to an electromagnetic wave that travels through space, i.e., transforms voltage into electromagnetic waves and vice versa.

What is a self-supporting tower?

Self-supporting towers are structures that require special attention under the dynamic actions generated by wind and seismic loads. … The results of the application of both techniques showed differences of less than 2% in the values of support reactions and tower displacements.

How tall is a telecommunications tower

The building is the pride of the GDR and the tallest structure in Germany, it has become a symbol of Berlin. Inaugurated on October 20, 1969, a few days before the 20th anniversary of the GDR.  Located in the center of Alexanderplatz, the heart of Soviet Berlin, it is a monument to socialist engineering.

The best time to visit the tower without large crowds is at noon, since most people come at sunset to enjoy the sunset from the viewpoint bar, the view from the viewpoint reaches on good weather days up to 70-80 km away.

From the Berlin TV tower you can undoubtedly get one of the best views of the city. Currently there is a tourist office on the first floor and on the rotating ball located 200 meters high there is a cafe with an incredible view of Berlin where you can see the city at a radius of 40 km.  The place is very nice and very trendy in Berlin. It is open until 00:00 h.

What problems do high voltage pylons cause?

It increases with humidity and has multiple consequences: noise emission, radiofrequency interference or the generation of tropospheric ozone. In addition, the corona effect causes the attraction and concentration of polluting aerosols and radon gas, especially in the vicinity of industrial areas.

What is the function of the pylons?

Transmission lines or high-voltage lines are made up of a conductor element (copper or aluminum) and supporting elements (high-voltage towers). These, once their voltage has been reduced to the distribution network, carry the electric current over long distances.

How tall is a Claro tower?

These structures are usually between 12 and 50 meters high and the antennas are located on top of them. In many cases these support structures are built with a design that allows them to blend in with the urban environment so that they have no visual impact on the surrounding landscape.

Height of telecommunication antennas

Good evening friends, after so much searching and looking all over the place, I got the concern of knowing how high my antenna can see. Everyone tells you more meters and more meters, but there must be a measure that fits the area you want to illuminate and that is not a waste of money, either because you spent and you do not reach or because it was not necessary to spend so much because you did not need so much height. I give as an example my case. The maximum I can achieve is 12m measured from the ground, and it is a mast. From there I said to myself, they say that in FM it is line of sight, like a flashlight or mini-vision, where it sees or illuminates, there it goes.

I didn’t know if my 12m mast was over that hill, thanks to this program I marked my mast base and put the street that is immediately above my head. From this it came out that my antenna base is 1333 meters above the sea and the street that I would like to illuminate and that is above my head is at 1348 meters. That is 15 meters difference. So with a height of 15 meters I could illuminate that street that is above me and settled on a hill from there on but at least 5 km more are still at that level. I hope it helps, I leave the program and search in Youtube:

What is the tallest telecommunications tower in the world?

Tokyo Skytree: The world’s tallest telecommunications tower.

What is the function of base station antennas?

The network of base stations makes it possible to move around without losing the conversation, as well as to establish a connection anywhere. In mobile networks, base stations transmit/receive radio waves that carry traffic in a given territory.

What is the usefulness of the antennas?

An antenna is a metallic conductor capable of emitting or receiving electromagnetic waves. There are therefore two types of antennas: those that emit and those that receive the signal. The function of an emitting antenna is to convert variable electrical signals into electromagnetic waves and to emit them, i.e. to radiate them.

Standards for telecommunication tower installation

The most important point of a tower installation is the correct fastening of the guy rods. These will determine the stability that the tower will have, and therefore, it is the point where we must be more careful.

It is always recommended to use a multi-strand steel retaining cable, galvanized by immersion (this is the one we commercialize). On the other hand, the use of wire of any gauge should be avoided.

A flange with collar support should be used at all times, to avoid friction and direct pulls on a tower leg. Tables of heights and distances can be found within our web site

Although not necessary for lifting a tower, a turnbuckle will help to maintain and fine tune the tension of a tower. There is no exact tension for all installations. Some installers tension with a value of 2 to 5% of the cable resistance.

Most likely following these steps, we will have an efficient and safe installation, however it is always recommended that a professional perform an engineering study in order to validate a correct installation of a structure.
