For a steerable. Not otherwise.

With multiple LNB's over a widish arc, the pole will need to be pretty
well aligned (but not as fine as for my 1.2m Fibo Gregorian)


No, you simply position the LNBs (up and down) optimally. If the
reflector is slightly non-vertical it doesn't matter. Obviously physical
fixings are easier if the thing is properly upright, but it can be made
to work even if the reflector is on a bit of a tilt.

The Wavefrontier T90 has to be skewed, as the vertical position of the
LNBs can not be adjusted. The dish is calibrated for skew, so if the
pole is vertical this is easier to do correctly first time.

The elevation can be adjusted by moving nuts on a screw thread.
