Got the more mobile setup working today with the re-purposed DirecTV slimline dish with the linear LNB bolted to it! Pulling similar numbers that I saw with the larger circular 90 cm dish, mounted on a tripod stand. As I almost lost the larger dish to the heavy winds we had blow through last night and overnight, I'm switching to this more stable DirecTV slimline dish...as it didn't move a inch during the heavy wind we got during that same time period. The larger 90 cm dish is way easier to tune, but catches more wind and has a tendency to suffer more from dish movement, resulting in signal attenuation.
