A new contactless method for online control tension of a radio-reflective mesh surface of a large-sized folding mirror antenna is presented. The method is based on revealing the correlation between Moire patterns and net-shaped curtain uniformity and tension. The advantages of the method are presented. Its main advantage lies in the fact that it is possible to set the net-shaped curtain on the folding skeleton of an antenna reflector in the online mode. The presented method is universal and can be used not only to manufacture antenna reflectors with the working surface in the form of a net-shaped curtain but also in any other structures in which the checked element is a net, regardless of the material of which it is made. A way to apply the method is presented.
