There is a lnbf BSC-621 series that does both C and Ku band reception. Most DVB receivers (that is what you are talking about here) do not control skew so using a feedhorn while possible is out of the picture unless you want to increase your investment.
If we are talking about mesh dishes there are 2 types. One has small holes and one large. If you can fit the lead of a pencil through the holes it is a large hole dish and only good for
C Band. Spun alum solid will work and older solid dishes are actually mesh dishes with a covering. From what many say they do not do Ku either. Your arc will be from 133 down to roughly 30 in the east and should be able to get with a 24" or longer
actuator. Providing the mount on your dish will allow that much travel.
Multiple dishes is an option but keep in mind you will need to use 1 of the 2 offerings from BSC on each dish. One uses a
DiSEqC switch to switch between C and Ku and the other uses 22 MHZ so My recommendation with multiple dishes is a DiSEqC switch prior to the dishes running separate lines out of the
BSC621-2 into port 1 & 2 of the DiSEqC switch. Use port 1 for C and port 2 for Ku. Port 3 on the DiSEqC can run to the out of the other lnbf and using 22MHZ off and on for the switch between the two bands on that dish.
You will need separate controllers for each dish for movement. I do not know anything about the receivers you listed but if they are capable fo moving the dish I would use them. They most likely can control a servo motor so using a feedhorn setup would also work but probably more costly than the BSC units.
Clear as mud yet?
