Dear Yunusa,

The selection of antenna size depends on the antenna gain you need. The required gain is arrived at by calculating the link budget. The following formula gives u the gain for any parabolic-dish antenna.

Gain(dBi)=20 Log (7.4 f d )

f=frequency of operation in GHz

d=antenna diameter in meters.
