Multi Satellite Dish

A multi satellite dish is created to receive satellites that are two or three spaced at a distance. The satellites being received will have 2-3 feeds and each feed has an LNB. The feeds must be spaced at a distance to fit the differences of the altitude pointing position and satellite azimuth. The dish serves as the reflector and outlines a reversed and inverted reflection of the numerous satellites along the arched line in the central region. The satellites in the sky as you looked due south form a arched line with the most extreme satellite signals on top. In this case, the central feed should be centered on the proper south satellite. The external feeds would slightly excessive while the left feeds will function with the right satellite as well as vice versa.

Most of the multi satellite dish available has pre-made LNB with fixed spacings. These spacings are essential especially if the dishes are to be utilized in the United States and for satellite receptions with spacing apart of nine degrees. The overall antenna of the dish can be rotated in order to position the angle of polarization. It can be optimized as well for the focal satellite.

A multi satellite dish with multi-LNB antennas may serve general purposes. The antennas can have five feeds. The main feed or LNB will be arranged first while the outer feeds will be positioned one by one. Every feed or LNB is required to be regulated in rotation or up/down sideways in order to set the polarization angle. Once the satellites are oblique from the south or southwest direction, the feeds will go down towards the southwest or will be in sloping line. For instance, you are on a position of 90 degrees west and you want to position to satellites in the west direction at 110 and 119 degrees. Such satellites are extended to the west than your current position.

In some cases the single feeds or LNBs of the multi satellite dish may be turned around in individual directions in able to arrange the polarization of the angles correctly. However, the dual or triple feed assemblage of the dishes is not changeable instead it should be fixed relatively to the overall dish. Moreover, the feed array of the dish should be turned around to set the average polarization of the angle accurately. The tilt or the rotation makes the line-up of the feed array with the satellite’s sloping line in the higher diagram.

Since the multi satellite dish is the reflector or mirror of the higher feeds, it receives signals from the subordinate satellite as well as vice versa. The right feeds of the dish receive signals from the left satellite and vice versa. In case of offset fed designs, the reflection point of the dish serves as the lower focal perimeter of the dish. The center of the dish along with primary feeds is maintained by three equal lengths. In installing a multi satellite dish system, it is suggested to wrap all with aluminum foil except one feed. This is to avoid confusion on which LNB or feed is to be used. Only single LNB or feed will work at a time therefore it should be lined up accurately and verified that it exactly points at the target satellite. Moreover, verify the list of satellite television programs and ensure that every program has a unique and identified satellite signal.
