Hi
I agree with snap & Iceman also. This dish is not of the highest quality and you definately need a Invacom/adjustable feed setup - you will probably also need a new LNB clamp as the universals are a different diameter. Please can you post a photo of the existing LNB assy so we can check and make a recommendation.
On the subject of ensuring the dish is assembled correctly I would recommend you use the old fishing line trick. I've a feeling I may be teaching you to suck eggs here but I'll explain for the benifit of others.......
On your dish I recommend you tie 3 lengths of thin fishing line between opposite petals on the dish. If you count the petals like they were a clockface 1-6, then tie midway between petal 1 & 4, 2 & 5, 3 & 6. Use thin Line & make sure they are tied midway between the petals.
All 3 lines will now intersect in the center of the dish. If the dish is perfectly set up then all 3 lines will touch WITHOUT pressing on another line. If this is the case then the dish is as good as its gonna get ('til the new LNB arrives)
If you find that a line is pressing on another then retie so the offending line is on top. You will now find that there is a space between the lines indicating a misshaped reflector assy. For small gaps, say under 1cm or so, then I recommend that you attempt to pull it back into shape. Have yourself and a helper pull back gently on the 2 petals that sit highest. Start with very small pulls and reassess after each try. For large gaps it may be worth reassembling the dish.
I hope that is of some help to you
Cheers
