582C75D8-5262-4078-9AEB-038AD36CDF0D.jpeg I have a Prodelin / General Dynamics 2.4 satellite dish.

I have been using a standard LNB for my satellite receiver. I have been using a standard cheap LNBF with a cheap bracket bent to use with this particular antenna.

When I purchased this dish, I did not fully understand that, in order to get the most signal out of it, I would need to use a special feed horn and LNB.

I have purchased the feed horn and the LNB is on the way, but I have some questions pertaining to how to connect the LNB to the feed horn.

First, since the end of the feed horn is circular, and the end of the LNB is rectangular, can I connect it directly or do I need some type of waveguide?

Second, since I will need a separate LNB for horizontal and vertical polarities. What do I need to connect 2 LNBs to one feed horn?

In my opinion you have at least 3 options. I will list them in my preference sequence.
1- make ne holder and install LNBF like Inverto Black Ultra (IBU);
2- adjust IBU to original Prodelin feedhorn;
3- mess around flange LNB connected to original Prodelin feedhorn, polarizer and other expensive stuff..

The Inverto Black flange LNBs are very good for this application.

But I also have PLL lnbs on an orthomode transducer.
