I didn't want to steal Satcom1's thread, so I am starting my own.
I was so inspired by his post, and just so happen to have a real life possibility that I am going to give this a shot and see what happens. I am hoping to get EWTN on Galaxy 17 C-Band along with whatever else I can get across the arc on C-Band plus all the Ku channels.
I am going to use my 1 Meter Primestar round dish and my SatAV CK-1 LNBF.
My son and I brought the 1M down from the roof yesterday morning, and I took down my motorized 84e and put that dish on the mount for Hispasat where the 1M used to be.
I wanted that motorized mount, because I put a little "extra" into it when I put it together such as an adjustable mast for setting the plumb, along with a real schedule 40 pipe.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I will be using my SG2100 for moving the dish, and have started putting together the scaler ring to hold the CK-1.
I shot some pictures while I am going through the project along with some numbers.
I will tune in the dish with the OEM Primestar LNBf first to make sure it is tracking the arc with USALS before going to the CK-1.
The focal distance to the OEM feed-horn is 28 inches. That is where I will try and set the CK-1 when I start that phase.
Here are some pics:

I didn't want to make new arms, and my opinion is that the LNBF should be held in place by it's scaler ring, so I started cutting and fitting. As it sits currently, the mouth of the feed-horn will be at 28 inches when recessed flush with the inside circle of the scaler. That would give a F/D of roughly .46 if that means anything on the CK-1.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I am also going to follow SatAV's choice in using a power passing on both sides splitter to allow the signal to go around the SG2100 instead of through it.
See SG2100 Insertion Loss thread.
Hopefully I can get the dish on the motor and start tuning later today or in the morning.
