[QUOTE="a33, post: 1134389, member: 332642"] A littlebit off-topic: Out of curiosity, I wondered: what would happen when you would only use such a bottom half, for reception? As that would give the best result, when you don't have a top half, I reckon. I just calculated: the 'new' dish would have height 1336.3, and offset angle 12.6 degrees (dish height opening angle towards focus: 48.1 degrees). Bottomstring stays 1460, topstring would be 1752. Distance Top of dish to G-spot: 718, Focus to G-spot 1527. So it would function as a 130cm dish, but a 'normal' feedhorn would give great spillover losses, I'm afraid. Not to recommend. However, when you have no other dish available, and are in urgent need of some sort of satellite reception, you could try it that way, and experiment... Back on-topic: I hope you can find a top half somewhere! Greetz, A33 [/QUOTE]
