Multi-satellite Systems

Multi-satellite systems

In this section we find the different equipment necessary for the reception of various satellites. This category is divided into 5 subcategories: satellite dish motors, multifocal LNB brackets, DiSEqC switches, stand alone multiswitches and cascadable multiswitches.

For reception of several satellites with the same satellite dish antenna we can use a satellite dish motor. This saves the positions of the different satellites and moves the disk to orient it to the satellite that we want to receive at all times. Another option is to mount a multifocus LNB bracket, which allows you to place two or more LNBs for satellites whose orbit is 3º, 6º or 9º apart. To see for example Astra 19ºE and Astra 23ºE, or Astra 19ºE and Hotbird 13ºE. For this we can also use 4.3º and 6º monoblock LNBs.

If we decide to mount several satellite dishes for a single-family home then we will use DiSEqC switches with as many inputs as there are satellites we receive. This equipment allows you to select from the receiver the LNB to which we want to send voltage to view the channels. The advantage is that we receive all the satellites through the same cable.

Finally, for collective distributions of several satellites and/or polarities, multiswitches are used, which can be autonomous or cascade depending on the number of dwellings in the community. In TDTprofesional we have stand alone multiswitches of up to 8 polarities (2 satellites) for up to 24 homes. For more than 24 dwellings, cascadable multiswitches would have to be used.
