[QUOTE="RimaNTSS, post: 901555, member: 312276"] Hi All! Last time I see more and more people mentioning that Gregorian type dish performs better than usual offset. So why do not we discuss here how to upgrade your existing offset dish to make it perform hopefully better up to 10%. So, idea is to design and make sub-reflector (SUB) which will fit your antenna. And all you need for calculations of SUB is illumination and offset angles of your antenna. What do you think about this idea? If we see that making of SUB is not plausible way forward, we can discuss how to use original Fibo SUB and attach it properly to another antenna (usually bigger) and still get improvement of performance.
