[QUOTE="DishDick, post: 875607, member: 216974"] Thanks for the input. I realise the F/D is important, but as I said, I understand an offset is effectively a portion of a prime focus, and if so, I thought that if you can increase a Famaval Prime focus by adding petals and the F/D stays the same (arms are not changed in the process and the feedhorn hasn´t got much play), then I thought the same must be possible with an offset. Obviously the angle of any extra petals is critical. I am just applying my own logic here, though it may be flawed. I have asked the manufacturer of my dish if they are planning to make any petals. I will let you know their response. [/QUOTE]
