[QUOTE="RimaNTSS, post: 969200, member: 312276"] OK, thanks for not going bananas and being ready for constructive discussion ;). We will certainly not go E=MC2 here, just very simple and easy manipulations with ruler, pencil, piece of paper and brains :rolleyes: First of all "Working area of the dish" -WAD (I like abbreviations :D ) ,what a hell is that? In my understanding, WAD is an area of the dish which receives signals (electro-magnetic waves) from satellites and reflects them towards antenna's focal point- point F. To find out where is WAD it is necessary to look closely to the edges of the dish (different dishes may have different construction of the edges, dependent on the process of manufacturing). I made this picture couple of days ago: Red line is parabola, blue line is the edge of the dish, and yellow line is oval which goes all around the dish and marks the WOD.

This is not so nice picture, as it is made on paper by me and [USER=181524]@Trust1[/USER] [ATTACH]92670[/ATTACH] And some pore pictures of the edges of WOD [ATTACH]92671[/ATTACH] [ATTACH]92672[/ATTACH] [ATTACH]92673[/ATTACH] [ATTACH]92674[/ATTACH] And this one shows how to reconstruct missing point B on antenna [ATTACH]92675[/ATTACH] Perhaps more to follow, anyway it is raining today.:rolleyes: [/QUOTE]
