[QUOTE="RimaNTSS, post: 897743, member: 312276"] I mean, dish should be straight, but if it is not straight lets not discuss how to make it perfect in shape, at least not in this thread. Here we will do some measurements on our existing dishes, and measurements will be correct only if dish is in perfect shape. Only then we will be able to calculate focal point. It does not make any sense to calculate focus of warped dish. Moreover, one of the measurements should be measured with very high precision and highly depend on antenna's perfect shape. My picture in first post is just an example, and not perfect example. Threads I used are too thick. But even with thick threads it is obvious that there is gap between vertical and horizontal cottons. [/QUOTE]
