Skew servo on BUD for FTA (newbie alert)

[Change]

I've noticed that the feedhorns for all BUDs have a servo for adjusting skew, but the only FTA receivers I've seen that make use of it are the Pansat receivers. None of the smaller dishes have any kind of receiver-controlled skew adjustment. Is skew adjustment necessary on BUDs for FTA channels?

My Manhattan receiver can control the skew, so Pansat receivers aren't alone.
