Device for setting up satellite dishes with your hands. Accurate and simple antenna tuning to satellite

To date, many people prefer satellite TV. However, it should be borne in mind that the antenna needs tuning. To this end, the market presents special devices that are able to determine the exact location of satellites. This process is carried out with the help of receivers. Capacitors are also used to change the threshold frequency of the signal.

It is rather difficult to assemble the device of this type at home. However, if you study the basic configuration of devices, then you can choose the most simple model for assembly. It is also important to remember that for proper use of the modification it is necessary to test it. The features of the instrument adjustment depend on the model type.

The device on beam transistors

To make this type of device for setting up satellite dishes by own hands is rather difficult for today. However, if you find all the necessary components, then you can understand this issue. First of all, a good receiver is being found for the device. Typically, it is selected asynchronous type. However, other modifications are available on the market. On the parameters they are very different.

The advantage of asynchronous receivers is their stability. They are also able to operate at high frequencies. After installing this component, you need to solder the resistors directly. To this end, you will need to use a blowtorch. However, the contacts before this must be cleaned with any metal object. Condensers for this model are more suitable field type. Their capacity is quite large, but bandwidths are sometimes disappointing. Filters for the device are most often selected corrective type. The display for the model must be selected separately. Directly the microcircuits for the receivers are used in class KK20.

Simple adjustment of the device on beam transistors

Tuning the satellite dish automatically takes place on short waves. First of all, the user must clear the signal. For this, the sensitivity of the device must be reduced as much as possible. After this, it is important to check the settings. As an example, you can consider the antenna "Hotberd". The transmitter is mounted on it short-wave.

The Hotbird satellite antenna is tuned at a threshold frequency of 50 Hz. Then gradually it needs to be increased. In this case, it is necessary to know the satellite data in advance. In this case, much depends on the type of receiver. After raising the threshold frequency, the sensitivity should be reduced. This should be done until the signal is completely reset.

Model with laser receiver

Make a device with a laser receiver for setting up satellite dishes with your own hands at home is quite difficult. First of all, the model naturally selects the case. In this case, displays are often used with a modulator of the P2P series. Directly zener diodes for the model are suitable only broadband.

However, some experts still prefer selective analogues. Install the receiver near the filter. At the same time, the zener diode is soldered in the last turn. To test the model, you need to use the Spectrum program. Triggers for instruments of this type are rarely used. The sensitivity parameter should not be more than 4 microns on average. Also, before checking the device, you must check the integrity of the receiver.

Easy tuning of model with laser receiver

Tuning the satellite dish automatically occurs at a frequency of no more than 30 Hz. In this case, it is necessary first of all to lower the sensitivity of the device. After that, the threshold frequency of the satellite is selected. If the display system shows an increase in the interruption of the signal, then the sensitivity must be increased. As a result, the user must have full synchronization with the satellite.

Using binary buses

Make a device with a binary bus for setting up satellite dishes with your own hands is not a big problem. The receiver in this case is more expedient to choose an optical type. It is worth it today is quite expensive, but it can work a lot. Resistors for models are suitable only for non-chromatic type. However, before installing them, the bus is directly soldered. Due to its use, the capabilities of the device are significantly increased. However, it should be noted that the modulator in this case can only use the P2P series. In this case, the filters for the system are selected correcting type. To test the model, you can use "Spectrum" (a program for setting up a satellite dish).

Precision tracking devices

To assemble the exact tracking device for setting up satellite dishes with your own hands, you can use a wave receiver. It is quite easy to find it in a radio shop. For the price it is not very expensive. Suitable for a receiver of this type are capacitors with a capacity of at least 5 pF. The filters deserve special attention in the device. Most often, they are selected based on the power of the resistors. As a modulator, chips of the PP20 type are often used. It should also be noted that binary buses for such modifications are installed quite rarely.

Devices with a latitudinal converter

This type of satellite antenna tuning devices (price market) are standing in the region of 3 thousand rubles. However, you can collect them yourself. They differ by a high parameter of the threshold frequency. In this case, the configuration process is quite fast. Receivers for models often used optical type. Total capacitors for the system must be purchased three.

However, their capacity should not exceed 3 pF. All this is necessary to ensure that the stability of the system is not violated even at a large clock speed. Zener diode for the model is appropriate to use angular type. However, wave distortions in this case can be quite serious.

Precise tuning of the model with a latitudinal converter

The adjustment of the device of this type occurs at a threshold frequency of 35 Hz. First of all, you need to set the satellite parameters to adjust the device. After that it is important to check the sensitivity of the model. The indicator in this case should be at the zero mark. The next step is to gradually increase the threshold frequency. In this case, the conjugation of signals is checked on the display. To regulate satellite television, ultimately the resonant frequency should stabilize. To test the device, the program "Ropit" is used.

The use of pulse converters

Instruments with pulse converters are quite in demand today. They are suitable for tuning antennas of a selective type. Receivers are most often used for devices optic type. In this case, the assembly of the model must begin with the installation of through capacitors with a display. In this case, the regulator can only be taken in a rotary type.

To stabilize the signal transmission process, only chromatic resistors are used. In this case, zener diodes are rarely used. A total of two thyristors are required for the device. One of them should be installed directly at the converter. The second thyristor is mounted near the modulator.

Application of cyclic capacitors

Devices with cyclic capacitors are used for tuning antennas for a long time. Receivers for them are very diverse. To assemble the model yourself, first of all you should choose the case. After that, the modulator is set directly to adjust the threshold frequency of the device.

The next step is to fix the capacitors on the chip using a blowtorch. Then there will be only to buy chromatic resistors. The converter in this case is advisable to use a pulse type. Many experts recommend using magnetic filters. The average sensitivity of the device must be at the level of 3 microns by default. For shortwave systems, such devices are ideal.

Setting up a model with cyclic capacitors

To adjust the device, it is necessary first of all to test it for serviceability. To do this, it is important to use "Spectra" (a program for setting up a satellite dish). The system is checked, as a rule, at a frequency of not more than 55 Hz. In this case, the sensitivity of the device should be located at a level of 5 microns. Only after testing you can proceed directly to tuning the antenna. For this purpose, the satellite parameters are selected first.

As an example, you can consider the antenna "Telecard." It refers to shortwave models. Setting up the satellite dish "Telecard" occurs at a frequency of 30 Hz. When setting parameters, you need to pay attention to the coupling indicator. If it deviates from its original value, then the sensitivity must be lowered. Next, a threshold frequency of 40 Hz is set. At this stage, the signal should stabilize.

Low-sensitivity modifications

If you connect a satellite TV, the antenna can be tuned using a low-sensitivity model. To date, it is quite common. However, her shortcomings are very significant. First of all, they are associated with poor stabilization of models. The receivers have only optical type.

At the same time, the sensitivity does not exceed 2 μm on the average. All this is caused by the fact that the filters in this case are suitable only for the magnetic type. However, the main advantage of the models is the fast tuning of low-frequency zener diodes. Thus, the conjugation of signals occurs rather quickly. For beginners such devices are ideal.
