[QUOTE="BombedOne, post: 548133, member: 300998"] Hello. I want to get big, and have large dish for satellite. The problem is - THE PRICE & availability. Each cm size increase, almost doubles price. Just check local ones: 120cm - $25 150cm - $45 180cm - $85 200cm - $200 240cm - $570 All these are solid dishes for Ku, no mesh or segment ones for C. I've researched various books and internet sites, and found some interesting results: 1. small sized (40-60cm) dishes can be made at home in 1-2 hour, with minimum materials required. 2. Some russian websites show selfmade offset panels, but they are aimed for multi-satellite reception, not for fringe zones, and also, involve huge amount of machinery. 3. In one book, I found most reasonable (in pricing and difficulty) method of making prime focus dish out of epoxy and fiber glass. But unfortunatelly, it only quotes dimensions of preform needed for 2m dish manufacture, saying that calculations are too complex (it lists all formulas, but I got lost in them), so better use predefined values and made 2m one. So here's questions: 1. Does anyone ever made dish by himself, 2. and, was it bigger than 2m ? 3. If done it, how, which method was used? Thanks in advance. [/QUOTE]
