Dear Vikram ji,
Since your dish is a prime focus dish, the focus for Ku-band is same as that for C-band signals. You can try attaching a Ku-band LNB and point towards Insat4B (DD Direct+) to check further.

Omparkash ji I have seen your dish, its really nice.
My dish has a f/D ratio of 0.371 and expected to give around 32dB gain for C-band and around 42dB gain for Ku-band with non-perforated reflector.
