[QUOTE="RimaNTSS, post: 902516, member: 312276"] Fishing was just great, had lots of fun and also caught lots of flatfish (I got ~40 of them). No need to calculate width of SUB, that will net be circular but oval. Vertical size of SB is always slightly bigger than horizontal. For feedarm for my 1,8m Prodelin I went universal way. This is support for LNB, adjustable in all directions. Something similar could be made for SUB as well. [ATTACH]69373[/ATTACH] Perhaps it is little bit too early (however I have some ideas about that). But, there is at least one, unsolved theoretical issue, to be precise that is tilting of LNB.... or Mizugutch condition. When I made drawings I made this tilt 22,6*, as offset angle of antenna, but in reality this tilting angle should be different. Appreciate if somebody could explain everything about this condition. This is very important for X-pol issues of Gregorian antenna. [/QUOTE]
