so far off topic it deserves its own thread
I would love to see someone design a mono-block 4 degree LNBF that would work anywhere in the US.
Absent that, a dish that would accommodate two standard dual feed LNBFs with 4 degree spacing.
I just ran the numbers, and it looks like an
84e could do 2.9° spacing using the small diameter
MINI LNBs.
There is some inherent error in my measurements.
Plus, I haven't tried this in all four corners of the USA.
However, it would suggest good potential for use on two birds 4° apart.
That doesn't get you both polarities.
But the Dish FSS bandstacked LNBs with the tall eliptical horns are the same width as the MINIs, so a couple of them should work.
Just a matter of a clever bracket that could rotate somewhat like the
GeoSat one they use on Glorystar.
Yea, I know. It's too big 'n heavy, too.
edit:
Well, now that we've come this far, two of the narrow horned FSS LNBs on a 36" GeoSat dish, spaced as that bracket measures, should give you feed for all the receivers you want.
Assuming that is a requirement.
I meant to write this idea up a few months ago, but it was a bit too technical for the Glorystar forum department, and I figured all the FTAers here wouldn't care.
