Title: Directv Plus Oval Dish
Post by Oortism on Jan 2^nd, 2006 at 8:09pm

I am setting up a Dirctv Plus oval dish for DishNetwork. My Lat. is 29 degrees and my Long. is 98 degrees. My Azimuth is 217.302752 and Elevation is 48.99856. Could you tell me what the "Tilt" drgrees would be for the dish? How does one calculate to find it?

Thank you very much---Oortism

Tilt, in this case, refers is the feed/LNB or entire antenna rotation polarisation angle, about the axis line towards the satellite.

The polarisation tilt angle is given on page https://www.satsig.net/ssazelm.htm

If you are aimed at a satellite due south of you then the tilt will be zero and feed/LNB/dish assembly upright.

If you are aimed at a south-west satellite then the rotation required is positive, so many degress clockwise, while facing towards the satellite.

Best regards, Eric.
