What is a multifeed for a satellite dish, how to choose a holder for a converter

After
setting up a satellite dish , the user gets access to dozens of interesting programs. But sometimes a subscriber may want to receive additional programs from other satellites but on one dish. In this case, he has the following options:

1. Each time , re-tune your satellite dish to the appropriate broadcast satellite . This is a laborious procedure, although quite affordable.
2. Set yourself two or more satellite dishes in order to cover all the satellites of interest to the user. Each of them will need to be configured. They will allow you to access all the programs you need, but there may be problems with the placement of antennas.
3. There are some types of antennas that do not require fine tuning to each satellite . They are able to receive all signals in a sector of 40-60 degrees. An example of such a device is a toroidal antenna.

   

4. You can get simultaneous access to several satellites from one dish using multifeed . In this case, several converters are installed on one antenna, fixed in the multifeed, each of which provides reception of programs from a specific satellite.

The last option allows you to solve the problem with the least cost and in the most convenient way.

Why do you need a multifeed, or is it easier to buy one holder than the entire plate assembly

User who views certain
satellite channelsmay be dissatisfied with their choice. For example, he wants to add some of them that are broadcast from other satellites. To remedy the situation, he must organize a reception from each of them. If the antenna meets certain requirements, then several converters can be installed on it at the same time. Each of them will provide reception from a specific satellite. Thus, the user will have access to all programs of interest to him. If they are paid, then you will need to pay to view. The use of multifeed is the least expensive option for watching programs from several satellites on one dish. In addition to the fact that this method of organizing satellite TV viewing from several satellites is the cheapest, but this method allows you to use space as economically as possible, which is especially important, if the antenna is installed on the wall of a multi-storey building.

1. The spread between the satellites, if we consider their horizons, should not be more than 10 degrees.
2. The use of multifeed is only available for antennas that are at least 80 cm in size.
3. There must be a power reserve for reception. It is about the following. If receiving channels using a single antenna requires its size to be 60 cm, then the multi-feed antenna must be 80 cm or more. If in the first case 90 cm is required, then you need to count on 110 cm.

If the user installs and configures the multifeed correctly, he will be able to watch channels from several satellites. The device in question will also be useful in the following situation. From one satellite, the user wants to watch TV programs, on the other – interesting radio programs to listen to, the third provides high-speed Internet connection. With the help of multifeed, it will be possible to use the services of all three satellites. The main elements for arranging a plate, in addition to the multifeed, are the following:

1. Satellite dish – mirror.
2. Converters , each of which is configured to receive a signal from a specific satellite. There should be enough of them to match the number of satellites used.
3. The switch (dysek) allows you to work with the selected converters. Their number depends on the number of inputs used, which depends on the design.

It is recommended that you purchase a switch with the required number of inputs.

What types of converter holders are there

Using a multifeed involves receiving a signal from two or more satellites. Varieties of designs are determined by the geographical location of the user, the number of converters used and the manufacturer of the equipment used. [caption id="attachment_3691" align="aligncenter" width="540"]
The size of the multifeed (the number of holders) depends on how many satellites the subscriber plans to “catch” on one dish

Installing and configuring a dish on a multifeed

To carry out the adjustment, it is necessary to find the optimal angle of the antenna and converters. In order to do this correctly, you need to better understand how the signals from the satellite propagate. They arrive in a parallel stream, falling on the rounded surface of the antenna. Reflected, the waves are collected at the point where the converter is located. This can be explained in the following figure.
As can be seen from the above diagram, if the waves arrive at a different angle, they will not enter the converter. Such an antenna will receive a signal strictly from one direction. If more than one converter is used, then the situation will be as follows.

As can be seen from the above diagram, if the waves arrive at a different angle, they will not enter the converter. Such an antenna will receive a signal strictly from one direction. If more than one converter is used, then the situation will be as follows.

However, the farther the converter is located from the central axis, the lower its received signal power. More than 25 degrees of off-axis signal level will be unacceptable for use. When installing the antenna, make sure that the direction to the satellites does not overlap. To carry out the installation, you must perform the following steps:

1. It is necessary to position the antenna vertically at the selected location. It is attached so that it has two degrees of freedom – to adjust the angle, location, azimuth and height of the satellite above the horizon. A balcony, a wall of a house or its roof is suitable as a place for installation. When installing, you need to do so to minimize the ingress of precipitation on the structure.
2. Assemble the antenna according to the operating instructions attached to it.
3. You need to install a multifeed frame on which converters will be installed. The antenna will need to be oriented so that its axis is directed to the satellite with the weakest signal. [caption id="attachment_3692" align="aligncenter" width="540"] Orientation to satellites
4. The converters will need to be fixed so that it is possible to make fine adjustments. The connectors for connecting the cable must be installed so that precipitation cannot enter them.
5. A switch is installed, which will subsequently be connected to the receiver via a cable.

During initial setup, converters do not need to be connected to switch. To configure them, you will need to connect each of them directly to the receiver. After the installation is completed, you need to start setting up the signal reception from the satellite.
Details on how to set up a satellite dish. To set up a multifeed, you need to start with one of the converters. It is connected to the receiver, and through it – to the television receiver. During the tuning process, the receiver and television receiver are conveniently located in close proximity to the antenna. How to assemble a satellite dish for three satellites using a multifeed: https://youtu.be/MTILwBtee2U If you need to hang it in a hard-to-reach place, then the setup must be done on the ground. In this case, you will have to use extension cords in order to supply electricity. To set up, you need to know the azimuth and elevation of the satellite. The antenna is installed in the indicated direction. Once connected, the receiver’s setup menu will be displayed on the TV screen. Here you will need to set all the parameters for receiving from the satellite.

If we are talking about direct focus, then in this case the level of the received signal will be significantly lower. Sometimes you can install a satellite dish only in a hard-to-reach place. You can set up a multifeed by assembling the structure on the ground. In this case, after installation in the right place, it will be enough to correct the angle at which the antenna is located. Calculation of the multifeed (location of converters) can be done using special programs links to download popular applications:

Online calculators for calculating the multifeed are also available: https://www.satcalc.ru/multifeed.php When making a bracket for multifeed converters, it is recommended to make it a little longer. This is beneficial for several reasons:

1. In the future, the owner may want to reconfigure the converters for other satellites. In this case, their location will change.
2. It will be possible to connect another converter.
3. Additional space may be required to make finer adjustments.

When buying a switch, you need to clarify compatibility issues with an existing television receiver. It is convenient when the installed model has several inputs.
