To get the LNBF in the right place there's
Parabola Calculator 2.0 click on WIFI tab for offset antennas.
Or at least very close accounting for measurement errors.
Then one could 'fine tune' with
polgyver's mirror method.
Nope, didn't know of that size CH. Master dish. [adding to the list] What is the vertical dimension?
Thanks, FaT Air, but I am rather an advocate (or, fan) of using small mirrors, as many members used them earlier, just to mention Cham, for example...
Another guy, Satcom 1 (from Chicago area) also recommended this trick when discussed his dish-making with Casser - it was on UK forum a few years ago, very long thread, 20 pages...
Attaching small mirrors is fun, when done with Scotch double-sided glue tape, and the mirrors do not impede reception. A few mirrors would do, although more can show if a dish is distorted.
As I did not figure out yet, how to insert a link in a post, the simplest way to see the mirrors on a dish is to google two words : ariza porch. Then see photo # 4.
TTSE : the small mirrors should be attached to the dish's "face" in various places, even randomly, but NOT on LNBF...
