ANTENNAS RADIATION MEASUREMENTS (HIGH FREQUENCY RADIATION MEASUREMENT)

We measure radiation from mobile base station systems

  • We measure the radar of Radar Airports
  • Radiation from all frequencies 5G / 4G / 3G, WiMax, Tetra, etc
  • We measure radiation in any broadcast antenna system Radio , Television
  • We measure radiation from 400MHz to 40,000MHz (40 GHz)

Fixed antennas used for wireless communications are called cellular communication base stations or cellular transmission towers.

In some cases transceivers and antennas are attached to the top of buildings, where the building itself provides the necessary height. The typical height of base station installations is between 15 and 60 meters. The radio signals are fed via cables to the antennas and then transmitted as radio waves to the area or cell surrounding the base station. Antennas used to transmit and receive signals to and from mobile users are usually about 15-30 cm wide and up to a few meters long, depending on their operating frequency, and consist of rectangular frames measuring approximately 0.3-1.2 meters (sector antenna)

However, in addition to the above antennas used for communication with mobile phones, the base stations also have dish-shaped antennas (dish antenna), which are terminals for microwave point-to-point connection and communication with other base stations for its interconnection. network. In some cases, base stations are connected to each other by underground cables instead of microwave connections.

Depending on the location of the base station and the number of mobile phone users served, the base stations can be a few hundred meters apart in large cities and up to a few kilometers in rural areas. Mobile networks are divided into geographical areas called cells, each of which is served by a base station. Mobile phones are the user's connection to the network. The system is designed to ensure that mobile phones are connected to the network as users move from one cell to another.

There are limits to the maximum coverage area of ​​base stations because radio waves are significantly attenuated as they propagate through the air. Regardless of the equipment, the power of the radio waves decreases sharply as we move away from the antenna. In free space, power is reduced to a quarter of the original when the distance is doubled.
In fact the power is reduced much faster due to the loss of signal strength (also known as "attenuation") caused because the radio waves have to pass through obstacles such as trees and buildings.
Antennas with transmitting power values ​​allow the transmission of radio waves over long distances, but beyond 35 km, the time required to transmit signals between mobile phones and GSM base stations increases significantly.

We shield buildings and detect Electromagnetic Fields that put areas, buildings and settlements due to the existence of Mobile Telephony base station systems.

Satellite parks for communication and links The radio telescope is a special instrument for receiving radio waves in the form of a directional radio antenna used in radio astronomy, but also in the monitoring of artificial satellites or spacecraft and in the collection of data transmitted to Earth. In their astronomical role, they differ from ordinary (optical) telescopes in that they detect radio waves instead of light.

Home appliances for various uses such as

  • Microwave ovens
  • Baby monitoring devices
  • Computer peripherals such as printers that connect to computers wirelessly
  • Wireless game consoles
  • Wireless Router
  • Wireless TV signal switches
  • Alarm systems
  • Wireless fire detection
  • Radio Networks
  • Low FQ Home Ovens
  • Large freezers with powerful motors
  • Army Airport Shipping Radar

Simply put, the radar is an electronic device that allows us to "see" our surroundings in the dark or in fog. In fact, it is a transceiver of electromagnetic signals that with appropriate electronic steps helps us to observe on its screen our surroundings, coasts, ships and aircraft, etc. It also allows us to calculate distances and views between "targets" and our boat. Depending on their use (eg for approaching aircraft, etc.) radars are divided into different categories.

We find them in:

◦ Airports
◦ Ports, marinas
◦ Meteorological services
. Military air bases

We shield buildings and homes hit by electromagnetic fields near antenna parks and airports

radio and mobile signal transmition antennas and towers

TV and radio antenna parks

A. Station: 'One or more transmitters or receivers or a combination of transmitters and receivers after the additional devices, which are necessary in a certain position to carry out (perform) a specific radio communication service or for the radio astronomy service. Each station is characterized by the type of service in which it participates and by whether it is permanent or temporary.

B. Antenna Park: Designated special area, where the creation and installation of antenna constructions is allowed.

C. Antenna park manager: The public or private body that undertakes the organization and maintenance, as well as during the general supervision of the antenna park.

D. Antenna construction: The system of radio transmitting and receiving antennas after their supporting constructions, components and accessories. Passive radio reflectors are also considered as antenna constructions. The height of the antenna construction includes the security lighting or the lightning rod.

We shield buildings and detect Electromagnetic Fields that put areas, buildings and settlements due to the existence of antenna parks in the area
