[QUOTE="BombedOne, post: 548288, member: 300998"] 1. Those simple dishes are made really simple - just take beach ball, inflate it as hard as possible, to maintain shape (big transparent ones), self adhesive aluminum foil. cut foil in stripes, and attach them to ball to cover approx 30% of surface, in dish shape. Attach LNB to opposite end of ball - you're done. 2. The book is about Microwaves in general, this is old soviet book (issued around 1987), it's dedicated for students, studying microwave transmission, and that dish project is given as training project for students. I think this book will be floating over internet - I'll try to find it. 3. No it doesn't. So you need to apply epoxy to back side of dish. 4. Regarding "SUPRAL offset dish 3700x4005". This seems to be too big and too weird. Are you sure about dimensions? Also, Russian dishes are very expensive. If you willing to buy from outside, take look at china. For example, 6 panel 240cm dishes start from $35 (0.5mm steel) to $120 (0.9mm steel). Regarding posting pictures and so on in this forum, it's quite hard, because this site works very strangely here. For example, I can't see my post for couple of hours, nor I can find "attach the file" link. [/QUOTE]
