[QUOTE="s-band, post: 985306, member: 407744"] BM, Journey, I've not had a good large dish before. The Winegard 3m was fine for C band but only a couple of dB better than the 1.5m on ku. That may have been more due to the LNB and co-rotor 2 though. It was a very deep dish and probably not illuminated fully on ku. Many thanks for the kind offer. I found a couple of references to it: [URL='https://www.satellites.co.uk/forums/threads/disaster.145302/page-19#post-741623']Disaster!![/URL] [URL='https://www.satellites.co.uk/forums/threads/what-systems-you-got-then.448/#post-1781']What systems you got then.[/URL] Have you any pics of the whole thing on the drum? I finally got the 3.8 drum out of the car. It is about 750mm diameter. [ATTACH]97570[/ATTACH] I got this because it was there (and Ebay failed st1 et al) so now I have some problems.
