[QUOTE="lanab, post: 797899, member: 384922"] They are not that bad if your dish is straight, i had a Winegard 1.8m petalized and it performed marginally better than a good solid spun 1.5m dish, maybe 1.6m.... If you look at test below from the 80's where they tested Alcoa 1.8 you will see the C/N is only like 1dB less than the best solid 1.8m dish, problem people did back then is that they didn't assemble the dish straight, they made the mounting holes larger and tried to force the panels which warped the whole dish, but mounted correctly it will not perform much worse than a solid one and mine was KU-band mesh antenna so it would have performed even worse in theory but keeping the mesh holes under 0.25mm it will not affect signal so much. Also my petalized Winegard had the famous "buttonhook" which sagged down so you need guy wires to have the focus spot on centered, otherwise you would loose another dB or so.... You have any instrument to compare it to any other dish at home? My old Winegard below, you will see the bad buttonhook, i hated it. [/QUOTE]
