The M6 16mm bolt on the elevation bracket is difficult to tighten up. The nut faced outwards and was impossible to tighten with a socket piece . I put a second nut and bolt through with the nut facing opposite, facing the wall which could receive the socket.\nThe LNB , I applied rubber boots to the F connectors and then was unable to close the shutter as there was not enough space.\nThe twin cable supplied was difficult to thread on to the F connectors as the covering was so thin, and in 3 places the braided wire was showing through, and will have to replace cable next year.\nThe SK 45 was good value and first time I had attempted an installation and was delivered in 3 days.
