Visvish bhai Please suggestion me How to set center scaller on this dish

 

[vishvish]

hello vikram , do you want to make it from offset dish to prime focus dish ?

 

[vishvish]

good set of dish's vikram , your 12 feet dish limited for one direction ?

 

[vishvish]

hello vikram ,

for prime focus parabola dish , all the need is focal point

here you can obtaine focal point by calculation

f = D^2 / 16d

f= focal point
D=daimeter of the dish
d=depth of the dish

you need to make new arms to suite prime focus point

IN fact there is no way, THe dish is itself offset, so where the lnbf is now is the focal point, If you think of this as a part of a large parabola, you will see that the lnbf right now is in the focus of the MOTHER-PARABOLA,
My suggestion, Always think of offset dishes as part of a larger prime=focus dish, Solves a lot of confusion that way,

Even if you insert or fix an lnbf somewhere in the middle it will show some signal, BUt that wont be the real focus, ut some signal receivable from some neighboring satellite (Just like a multi-lnbf

well QB we can still concider this above dish as whole parabola , while its shape is not in oval shape , ? what you say ? while the prime focal lenth will be different
