F/D cal of offset dish

Can anyone tell me how to calculate the F/D Ratio of a offset Dish
so that I can build a 10G feed for it. The original feed was at a focal
length of ~44.4cm.
My dish is 66cm X 60.6cm and is 6.5cm deep. I don't think the cal. for a
round dish is what I want to use.
TNX for any help
