needed to clear the cobwebs
Sorry - I didn't understand your question at 5am.
Now, it makes a lot more sense.
Ya wanted more World dishes for their LNBFs?
I wouldn't be too concerned.
That LNB is probably just average.
The feedhorn matches (that) elliptical dish.
Yes, you could mix 'n match components to make up something special.
But I wouldn't design/build around a rare component, with so many other choices available.
On the other hand, if you DID find a cache of World dishes, I'd put 'em up for any bird with only DVB-S .
Skip the hard-to-get S2 stuff. Or at least test it last.
97•w and 30•w might be good candidates.

Just remember to skew the dish.
