I have a Dishnetwork super dish that I bought before I determined I can't use it in my location. (Too many trees to for the low hanging 121, 105)... Can I use it to get a better signal for satellites 110 & 119?
The answer is probably NO even though the Stupid DISH is larger it is a compromise design to get three locations and probably won't get any more signal than a dish 500.
The fewer lnb's a dish is designed for, the stronger signal you will get (surface area being equal), that's why these multiple lnb dished must be larger, just to keep up.
