[QUOTE="Analoguesat, post: 1022244, member: 176362"] Ah interesting - radio astronomy is an unusual topic on this forum. :) If its going to be enclosed then distortion from bad weather can be reduced. You can use a technique known as "stringing" to see how accurate the dish is - run threads across the face and they should be virtually touching in the middle. If there is a gap of more than a couple of mm then the dish is warped / out of alignment. It is possible to correct warped dishes with a bit of time & skill. [/QUOTE]
