[QUOTE="jeallen01, post: 1051973, member: 176704"] In my (limited!) experience, the types of LNB brackets (commercial and "home-made") shown in the posts above won't suffer much in high winds because they are very short. However, if you use/make brackets that are a lot longer than those, then support arms at the outer ends may well be necessary, and not just in high winds, because they will have a tendency to move up/down due to the wind and/or any accidental contact by "something else" (such as my head/arms on the brackets on my dishes which are at ground level!) as a result of the natural flexing of the bracket(s). Also, if one of the brackets is much longer than the other, then there is a tendency for the sheer weight of the bracket and the LNB(s) will tend to cause the whole arrangement to droop on that side. Either/both of those factors is likely to make it difficult for you to ensure that the outer LNB(s) stay accurately aligned on the relevant "sweet spot(s)" on the dish. [/QUOTE]
