Point your antenna towards HISPASAT
The new orientation programme to enable you to direct your satellite dish towards HISPASAT satellites, will allow you to select the country you live in, be it in Europe or North Africa or in America, and the satellite you wish to direct your satellite dish towards.

Orientation and Direction
|
In order to receive HISPASAT transmissions, a satellite dish can be installed on a rooftop, terrace, windowsill or in garden with an unblocked view towards the SouthWest, that is to say, without obstacles or geographic impediments which block the direct view from the satellite dish to the HISPASATsatellites. These are located at a 30º West orbital position (in the middle of the Atlantic) and a 61º West orbital position (over Brazil). Correct antenna orientation first requires finding the basic position of the satellite dish.
This consists of determining the satellite dish’s azimuth, elevation and polarisation plane value. A table-map has been included on this page, with the azimuth and elevation values for all of Spain's capital cities. Calculating the adequate parameters for any other zone can be obtained by using the rapid calculation programmes provided in the following pages and inserting the values specified in the map included in the following figure.
In any event, a fine adjustment using a field meter, which tunes into the open channel, is always recommended.

Azimuth
|
The azimuth value will indicate the exact point at which we should position the satellite dish within the South West arch. This angle is measured clockwise from the geographic north.
Once this value has been obtained and with the help of a compass, we can direct the satellite dish towards HISPASAT. For example a dish installed in Barcelona (Azimuth 223) should be positioned at 223º.

Elevation
|
The angle of elevation will indicate the inclination of the satellite dish with respect to the horizontal plane so as to be able to direct it towards the HISPASAT satellites.
The approximate elevation value tends to be an angle close to the complementary latitude angle. That is to say, diminishing angles as we move towards the North. For example, in the Canary Islands or in the South of the Peninsula, the angle of elevation will be greater than in the North of Spain.
Once the angle of elevation has been obtained, the antenna can be adjusted using the graduated scale engraved on the back of the satellite dish. For example, the angle of elevation of a satellite dish to be installed in Cadiz would be 41º, but in Bilbao it would be 33º.

Adjusting the plane of polarisation
|
The polarization plane is adjusted by turning the converter (LNB) clockwise with respect to the vertical angle of the fixed plane. Values for this angle, which also varies according to the antenna’s geographic location, are included in the following graph.
