Advice 1: How to strengthen the radio signal

Sometimes the signal level at the input of the radio or TV is insufficient for reliable reception. In these cases use the external antenna, including directional and antenna amplifiers. Their use sometimes able to approximate the reception quality to one that provides collective antenna.
How to strengthen the radio signal
Instruction
1
For the reception of long, medium or short wave good outdoor antenna. It is a wire with a length up to several tens of meters, suspended at a height of about twenty meters. Such a structure is rational to build in rural areas. Outdoor antenna must be equipped with gruzopoluchateljam and ground during a lightning storm. Operation without grounding and gruzopoluchatelja not allowed.
2
In the city, and in the absence of the desire to set gruzopoluchatelej, for admission to the same ranges you can use the indoor antenna. This is a piece of wire with a length of several meters, laid on the ceiling, and if you live on the first floor - even on the floor. Ground the receiver in the application this antenna is optional.
3
Loop antenna for reception of short wave consists of a single square loop of wire with sides of one meter. For this round of connect variable capacitor with the upper limit of adjustment of about 350 picofarads. One of the conclusions of the capacitor connect to the antenna input of the receiver.
4
Reception of ultrashort waves on any receiver except automotive, can be improved by using antennas with a length of about two meters. To do this, take a piece of wire of appropriate length and to one end solder the clip. This clip is put on the telescopic antenna of the receiver.
5
The receiver is usually able to take the station in two ranges: medium and ultra-short waves. In order to increase its sensitivity, you will have to use a special antenna with built-in amplifier. Note that under the guise of such amplifiers are often sold empty boxes on which only the led. Not to run a fake, buy them in safe places.
6
TV antenna for improved reception supplied with amplifiers, which are placed in close proximity to them. You can buy an antenna in which the amplifier is already there, and you can buy one for your existing antenna.
Power is supplied to it not on a separate cord, and on the same cable that the antenna is connected to the TV. The amplifier includes a distribution device consisting of a throttle, through which it is powered, and capacitor, on which cable the signal is received. The same splitter have a special antenna connector that is included in the device. Usually it is attached and the power supply, pre-attached to Takeru. But the coaxial cable of the desired length will have to be purchased separately and lead from the TV to the antenna with the amplifier on their own, guided by the instructions for the device.
7
To cell phone worked better, say, in a metal construction trailer, install it on the roof of a small TV antenna without any amplifier. The cable from it, draw the window of the trailer, desolder from the connector, instead solder to the copper core of a piece of wire with a length of eight inches. Use the phone, holding it next to the piece of wire.

Advice 2: How to increase antenna reception

The quality of television and radio signal does not always satisfy the viewers and listeners. Moreover, interference can be the case even when there seems to be a bigger antenna. In order to improve the quality of reception, the antenna should be configured correctly.
The sensitivity of the antenna largely depends on the effective height
You will need
  • coaxial cable, portable radios or mobile phones.
Instruction
1
Effective height of the antenna is one of the most important parameters that determine its sensitivity. Therefore, to improve reception , raise the antenna as high as possible above the ground, regardless of whether it is on radio or television.
2
If the antenna is aimed, try to reinstall it so that between it and the signal source there is no interference. Such obstacles can be tall buildings or other structures, power lines and so on. You can try to fine-tune the direction to the source signal. You can use the assistance of an observer, a control signal at the receiver. For communication it is possible to use a portable radio or mobile phone.
3
If you have a directional antenna with a flat polarization (type "Wave channel" and the like), check the polarization of the received signal. Configure it according to the data obtained. For this you need to rotate the antenna about an axis aimed at the signal source. Often simply try to rotate your antenna by 90°.
4
The efficiency of the antenna can be improved by the antenna amplifier. But in this case, the gain limit is set by the noise level. To reduce their level use shielded reduced, that is, the antenna is best to connect using coaxial cable.
5
The efficiency of the antenna, especially when receiving long, medium and short wavelengths can be improved by installing additional ground. It should also be borne in mind that the antenna must be matched in impedance to the input circuit of the radio. That is, it is necessary to connect the type and brand of cable recommended in the instructions to the receiver or TV.
Note
Antenna long, medium and short waves can be a piece of wire lengths. The suspension point of such antennas is also recommended, based on the highest volume receiving the desired stations. It is necessary to change the position of the antenna.
Useful advice
If we are talking about indoor antenna, the best solution is to install a fixed external antenna. This will dramatically improve the quality of reception. Are also external antenna it is recommended to connect the portable mobile radios and televisions during their operation at steady-state conditions.

Advice 3: How to strengthen a cell phone signal

Cellular communication has long become a convenient means of communication. However, it has its weaknesses and limitations. One such gap is the weakness of the signal of cellular communication when removed from the repeater. To enhance the cellular signal and improve mobile telephone of GSM standard uses a special system, the installation of which consists of several stages.
How to strengthen a cell phone signal
You will need
  • System cellular signal amplification
Instruction
1
The installation of the system gain cellular signal , start with the installation of an external antenna. Select the place for installing the antenna. When selecting a location, consider the number of floors, placement of the amplifier, the presence of neighbouring buildings. The main criterion – the input to the amplifier must receive a signal of maximum amplitude.
2
Determine the optimal length of the connecting cable. Cable length from external antenna to the cellular amplifier needs to be kept to a minimum, this will reduce loss of signal. Alternatively, the antenna can be placed on the roof or on the mast through the bracket. If this is not possible, the antenna location may be the facade of the building in the vicinity of the amplifier. This option is useful for amplifying the cellular signal in small offices, cafes and restaurants on the lower floors of the building.
3
Select the correct direction of the antenna, orienting it so that the level of the signal of all available mobile operators were approximately the same. Otherwise, there will occur a clear predominance of the amplitude of the signal carrier.
4
Make the crimp connector cable and connect it to the receiving antenna. Connector seal with heat shrink polymer tubing or insulating tape.
5
Route the cable from the receiving antenna to the booster signal. In this case, consider the building rules and regulations, and especially the RF cable. If necessary tighten the cable in the corrugated pipe. Consider also the bending radius of cable the thicker the cable, the greater must be the radius of the bend to avoid losses and change in estimated values of the level signal.
6
Select the location for installation of cellular communication. This can be a attic, utility room or basement where there is a possibility of connection of 220 V. the optimum positioning of the GSM repeater in the attic to minimize cable length and to provide a high-quality signal. Keep in mind when selecting a location for the amplifier that even in summer the temperature in the installation place should not exceed 60oC.
7
Connect the external antenna to the amplifier input. Before connecting, make dimension of input signal connector. If readings are normal, again adjust the orientation of external antenna by aligning the signal level of all operators of cellular communication. Then insert the cable into the connector on the amplifier input. Connector screw with a force to ensure good contact. Produce a sealing of the connection of the connector and the input of the amplifier for cellular communications using adhesive tape.
8
Refit the power dividers and the internal antennas. If the internal antennas is two or more, the gain signal is set to the channel splitter (power divider).
9
Configure the power connection. To do this, after installation the whole system first, give her the supply voltage. Connect the repeater to the mains without load is prohibited, as this may cause damage to the device. Make setting in accordance with the technical documentation to a specific type of amplifier.In the basic version, the GSM amplifier amplifies the signal for all major GSM operators (MTS, Beeline, MegaFon).

Advice 4: How to boost the signal to the TV

To send the image to the TV was as clear as possible, the desired signal is of sufficient strength. It is often not enough, which causes interference. Amplify the signal several ways, depending on the connection type television.
How to boost the signal to the TV
Instruction
1
Install the reason of weak signal. If you are a subscriber of cable TV (problems with signal strength here are rare), first of all, check the integrity of the cable. Perhaps its somewhere twisted, passing. This could disrupt the signal.
2
To solve this problem you can either contact the company whose party you are. Need to cut out the damaged area of the cable and solder the adapter to re-connect. After performing all these manipulations will be no need for signal amplification.
3
Follow the same steps if you use receiver of a satellite dish or a conventional TV antenna. The signal may be weak due to the fact that you have installed the device, ignoring the simple rules outlined in the instructions. Have in mind that the antenna you need to install on the side of the house where there are no significant impediments to receiving a signal. This can be a big tree, tall building or some other large object. If the antenna is installed correctly, check the wiring. Perhaps this is the reason. Eliminating connection problems, you can boost the signal.
4
Buy a more powerful receiver. This device can amplify the signal for TV. Plug it in, following the rules outlined in the instructions for the installation and operation of the device, or refer to the appropriate specialist. The receiver is an integral part of a network of satellite dishes. It depends on the number of channels and the clarity of their reception. Even if you have a heavy duty antenna, but a low-quality receiver, this can greatly affect the quality of the received signal. If it comes to ordinary TV antenna, try to choose the optimal direction of capture signal. This will solve the problem of the quality of transmission.

Advice 5: How to strengthen a cell phone signal

To provide radio coverage of the entire country for operators of cellular communication is not economically feasible. Therefore, base stations are placed more densely in places of the greatest congestion of people, in the villages, their density is much lower. This leads to the appearance on the map of "dead zones" and "zones of uncertain reception of a radiosignal". To improve the quality of communication when unsure of the reception signal by using a repeater, an additional antenna or an antenna amplifier.
How to strengthen a cell phone signal
You will need
  • repeater complete with external and internal antennas, coaxial cable, connectors and power divider;
  • - bracket for mounting an external antenna;
  • - crimping tool, knife, wire cutters and duct tape.
Instruction
1
Pick up the repeater taking into account the required power and frequency range that your mobile telephone: GSM-900 or GSM-1800. To improve the quality of radiosignal in the country or in a country house, it is sufficient to use a low-powered repeater, medium power amplifiers are used for several houses, and a powerful repeaters can provide communication to a small village.
2
Connect to an external antenna one end of coaxial cable and attach it using the bracket on the facade or on the roof of the building. An external antenna is typically used, a directional antenna with high gain. Point it toward the antenna of the base station located at the nearest tower of your operator of cellular communication. Antenna try to place as high as possible.
3
Route the cable to the installation location of the repeater, pin it on the appropriate connector. To do this, replace the cable heat shrink and a metal ring, strip the Central vein, and set her "needle". Secure with a crimp connector on the cable.
4
Connect the external antenna to the repeater, designed to amplify a radiosignal in two directions: from cell phone to base station and back. To eliminate the mutual influence of the antenna position the internal antenna at a distance of not less than 20 m from an external antenna.
5
To increase the coverage area of the repeater, connect via voltage divider multiple internal antennas with circular radiation pattern, using a cable with internal impedance of 50 Ohms.
Note
When you connect the repeater to the antenna, use a short coaxial cable. The longer the cable, the more it attenuates the signal and the worse the link quality.
Useful advice
For good reception of radio signals from several mobile operators use as an external sector antenna or install multiple sets of equipment.

Advice 6: How to strengthen communication signal

In the life of almost every owner of a mobile phone of the GSM standard, a situation arises where it is necessary to strengthen the signal of the cellular network. In the area of the base station of any operator of when there are places where the signal is weak or completely disappears. This "dead" zone. They can occur both indoors and outdoors, but there are ways to strengthen the signal connection.
How to strengthen communication signal
Instruction
1
Indoors cause "dead zones may be concrete walls and floors that might obstruct the radiosignal. This is especially true for basements. To help in this case, you can install a special amplifier cell signaland or a repeater.
2
The distance between the internal and external antenna should not be less than 20 m. the Use of repeaters is especially important for vacation homes and rural areas.
3
On the roof of the building, install an external antenna (a small device that is sold in the store). Send her to the nearest and least loaded base station of the operator of cellular communication.
4
The external antenna is connected by cable to an amplifier, cell signal. Adopted and amplified signal is supplied to network, GSM device, modem or mobile phone. If the area is large, you can install multiple internal antennas and the power divider. Such antennas are usually mounted on the ceiling.
5
A repeater is an antenna amplifier cellular signal. Included with it are the external antenna, one or more internal antennas and the power divider. Connect all this equipment is coaxial cable.
6
If there is a need to ensure that the signalissued a few houses or premises with an area of more than 10,000 sq m required installation of repeater high power, and in some cases you will have to use a booster device for intensifying action the primary mechanism, in this case repeater.
7
Amplifiers the signaland the cellular network is absolutely harmless to human health. The power of radiation five times less the power of a regular mobile phone.
