The invacom has a quad linear/circular LNBF. Love it.
But........
By chance does anyone make a quad linear/circular UNIVERSAL lnbf that will grab lower/upper bands?

I know I'm asking a lot, but doesn't hurt to ask. It would be nice to be able to pick up every signal possible with my brought back to life USALS KU system. I mostly have fixed dishes on all the popular KU birds, so the only real purpose of my USALS KU is to be able to pick up everything else.

I ordered a Quad Universal LNBF, but that leaves me out of the birds that have circular polarities. I may hook in a 4 degree side lobe for Circular, which would probably work, as those signals tend to be very strong.

Okay, that is just AWESOME. Never knew... Do you have model numbers or is this just a very COOL hobby build that you cannot currently purchase.



The original designer to this modification is a gentleman who goes by the name of Lambda, he is making another one at the moment for a new project on his new Laminas 2.7m antenna he is adding a laser to his next one,

The modification in the video below was on his old 2,4 now sold.



 
very cool, and definitely interesting, but i have to wonder why so many LNBFs. I can see the need for 4 of them: C-Linear, C-Circular, Universal Ku Linear and Universal Ku Circular. Ok maybe also a few variations of Ka (which I'm not familiar with at all), and maybe the exotic 4.5-4.8 GHz C-Band (which exists in Linear and in Circular).

But the 2nd video shows what looks like 5 Ku LNBFs...

Hi yes KA band four LNB is needed to cover the whole spectrum I am unsure if he hunts extended c band but he could do.

Old picture of C- circ / C-lin / KaKu combi / Ku lin / Ku circ / SL3K at 1.8 m Channelmaster
Now also a modded Ku lnb attached for EsHail 25.5º E (10.300 - 10.700 Mhz)
