Fixed dish and motorised dish together through diseqc to one stb

[Huevos]

On an 80cm all those satellites are too many, in my opinion. Some of the transponders are not going to work. Also if you have more than 4 LNBs you are going to start spending money on expensive uncommitted switches.

What I would do is this. 28E, 23E, 19E, 13E on an 80cm dish. Put whichever is the weakest at the focal point. 23E probably. Dual output LNBs.
Second dish on a motor. Hopefully this will be a 90cm or 1m dish.

Tuner A, DiSEqC to 28E, 23E, 19E, 13E on an 80cm dish.
Tuner B, DiSEqC to the three most used satellites on the fixed dish and the fourth port to the motorised dish.
