More the number of ribs, more well-defined and strong is the shape:

Mark the points on the ribs where holes have to be drilled to be able to cover it with metal mesh/sheet.

A rod of length same as the calculated focal length of the parabolic reflector is to be taken and the conical scalar ring of the LNBF should be fixed to it.

Thanks Sathish bro,

Yes you are right. This is a 4 feet (120cm) dish and is good for people who have space crunch on their home terraces or cannot fix a big bulky dish.
Another good thing is the ease with which it can be assembled/disassembled with no bulky parts.
The results of this dish amazed me. The signal quality and picture/sound stability is more than expected.
More details will be covered in this thread later.
