In the era of communication and technology, access to clear and noise-free television images is one of the basic rights of the residents of every building. With the expansion of urbanization and the increase in the number of residential units in apartments and towers, the use of personal antennas is neither rational nor practical. Imagine the roof of a twenty-unit complex covered with twenty separate antennas; Not only does it give an ugly look to the building, but the interference of the signals causes a decrease in the quality of the image. In such a situation, the need for an integrated system is felt. In the city of Hamedan, Electriki Milad, which provides central antenna installation and repair services, is known as a specialized and reliable authority that makes the experience of watching TV enjoyable for residents by using modern knowledge and advanced equipment.
Why is central antenna system (MATV) necessary?
The central antenna system or MATV (Master Antenna Television) is an engineered solution for receiving, amplifying and distributing television signals among a large number of receivers. But why is this system so important? First of all, the issue of building aesthetics is discussed. Removing the forest of stray antennas and cables on the facade and roof restores visual order to the building. Second, there is the issue of signal quality. Individual antennas are usually affected by physical obstacles and frequency interference, but Electriki Milad, a provider of central antenna installation and repair services, with accurate engineering calculations, receives the signal at the best point and delivers it to all units with standard power.
Furthermore, maintaining a centralized system is much simpler and less expensive than maintaining dozens of individual antennas. When you use the services of a group that Electriki Milad provides central antenna installation and repair services, you are actually investing in an infrastructure that increases the value of your property and ensures the comfort of residents. In the high-rise buildings of Hamadan, strong winds can displace ordinary antennas, but the central antenna masts and equipment installed by Milad experts are resistant to the harshest weather conditions.
The main components of the system and the role of parts quality
A central antenna system consists of different parts whose coordinated operation guarantees the output quality. These components include the receiving part (antenna and converters), the amplifying part (amplifiers), the dividing part (splitters and tap-offs) and the transmission part (coaxial cables). Electriki Milad, providing central antenna installation and repair services, does not only focus on skilled manpower, but also supplies the best brands of equipment.
Using low-quality cables or fake amplifiers can paralyze the whole system. Video noises, rasterization of the image, and disconnection and connection of the signal are often caused by quality loss in the equipment. For example, the correct choice of coaxial cable with all-copper shield and core plays a vital role in transmission without signal loss. Elektriki Milad, a provider of central antenna installation and repair services, with a detailed knowledge of the products available in the market, guarantees that all consumable parts meet the highest global standards so that customers do not face problems such as signal loss in the lower floors.
The basic installation process of the central antenna by experts
Installing the central antenna is not something that can be left to amateurs. This process requires accurate decibel (db) calculations and network topology knowledge. Elektriki Milad, the provider of central antenna installation and repair services starts the installation process with a detailed field visit. At this stage, using advanced signal measuring devices, experts identify the best spot on the roof that has the highest level of reception and the lowest ambient noise.
After placing the antenna, it is time to design the distribution network. Whether the cabling is done as a tree (Tree) or a star (Star) depends on the piping structure of the building. Elektriki Milad, a provider of central antenna installation and repair services, by examining the plans of the building's electrical facilities, chooses the most optimal route for the cables to be used so that the least amount of cable is consumed and at the same time, signal loss is minimized. Installing and adjusting the amplifier is the beating heart of this system. If the amplifier power is less than required, the lower floors will not have a signal, and if it is too much, the image will be distorted. Precise adjustment of "gain" and "slope" of the amplifier is an art that Milad electrical technicians are proficient in.
Troubleshooting and specialized repairs; Distinctive service
Even the best systems may suffer from environmental factors, wear and tear of parts, or manipulation by non-specialists. In such cases, speed and accuracy in troubleshooting are the first words. Electriki Milad, a provider of central antenna installation and repair services, has a quick response team to fix breakdowns. Common problems such as "No Signal message", rasterization of the image in some networks, or the presence of shadows in the image, each have their own technical reasons.
Unlike traditional repairmen who proceed with the trial and error method, the experts of Elektriki Milad, the provider of central antenna installation and repair services, use frequency spectrum analyzer devices to find the exact location of signal loss or failure. The problem may be water infiltration into the cable, oxidization of the plug connections, burning of the power supply of the amplifier or failure of the LNB. The quick diagnosis of the problem will reduce the repair costs and allow the residents to have access to TV channels again in the shortest possible time.
The importance of choosing the right amplifier in big projects
One of the main challenges in large residential complexes and towers is signal loss over long cabling distances. Here the role of line amplifier and multiband amplifier is highlighted. Elektriki Milad, a provider of central antenna installation and repair services offers an amplifier that has the ability to overcome the ohmic resistance of cables with accurate cable loss calculations.
In projects with a large number of receivers (such as hotels or hospitals), the use of advanced "head-end" systems is necessary. These systems have the ability to receive signals from different sources (satellite, aerial antenna, CCTV) and integrate them on one cable. The implementation of such complex systems requires high technical knowledge, which fortunately Electriki Milad, the provider of central antenna installation and repair services has, and has a brilliant record in implementing large projects in Hamedan city.
Standardization of cabling and connections
Perhaps it can be said that the most important factor in the stability of the central antenna system is the quality of cabling and connections. Using standard RG6 cables with a dense woven shield prevents electromagnetic noise (such as mobile phone or elevator noise) from penetrating into the system. Electriki Milad, a provider of central antenna installation and repair services always emphasizes the use of all-copper cables and waterproof press plugs.
Loose or oxidized connections are digital signal killers. In today's digital systems (DVB-T2), the slightest interruption or change in impedance can cause the picture to freeze. The technicians of Milad Electric, providing central antenna installation and repair services carefully check and tighten all the connections in the splitters and tap-offs to ensure the stability of the image in all seasons of the year. Also, observing the principles of connection and earthing of the central antenna system to prevent damage caused by lightning or power fluctuations is an integral part of the services of this collection.
Fixing the problem of jamming and frequency interference
In urban environments, disturbing waves and jamming can negatively affect the quality of network reception. One of the specialties of Milad Electric, providing central antenna installation and repair services, is providing solutions to filter these noises. The use of directional antennas with high "gain" and LTE noise removal filters (related to mobile towers) can make the reception of TV signals pure and clear.
Sometimes residents of one unit complain of poor picture quality while the unit next door has no problems. This issue is usually due to tampering with the floor divider box or the use of low-quality splitters indoors. The technical team of Milad Electric, which provides central antenna installation and repair services checks the signal path from the roof to the outlet inside the house, opens the blind nodes of the network and balances the signal.
