Site Selection for PDA(Parabolic Dish Antenna) : Communication and TV Broadcast satellites are located at a distance of 36000 kilometers in a geostationary orbit. India is stable in the northern hemisphere of the earth. In other words, the equator is in the southern part of India.Because of this the PDA face is facing south, and it has to rotate 90 ° west and 90 ° east.
Some professional TVRO the use of big PDA in the operating system. In that case, the azimuth system can be used on both sides at 30°. W Satellite tracking must be within range while doing this.Fix the Foundation by checking this deadline. Foundation is easy if the Azimath Range is 180 ° or over.
When installing PDA,you need to know the location of the service satellite. The latitude and longitude of the satellite location are given by PDA. The azimuth and evolution calculates can be let the PDA.If there is a large building to the south near the place of installation, an incorrect installation occurs. There should not be tall buildings or trees to the south of PDA.
Lightweight and low diameter PDA, they fit on the tall building. Satellite receiver is kept close to the PDA. Short length cable is used to to prevent further loss.This cable should not be longer than 20-30 meters.The location must have a mains power supply.
