This particular antenna s true pointing axis will be 22.8 higher than its apparent pointing axis. Refer to figure 6 . I ve tilted the antenna back 19.4 from vertical. Add 22.8 to that number and the actual elevation angle is 42.2 . If this antenna were pointed toward the hypothetical satellite discussed earlier, this is how the antenna would look.
Some designs are wider than they are tall.
The dish should be pointing straight up. Fill the antenna with water it may be necessary to seal bolt holes to keep the water from leaking out until the water just reaches the top and bottom edges. The water in the dish should have the desired oval shape that is, taller than it is wide. Measure the height and width of this oval and plug those numbers into the tilt angle equation. Proceed with the steps detailed for the DBS antenna.
