Does we interpret this correctly when we say: this antenna is parallel
to the earth in the satellites nadir?

Does it mean that:
  all main mission antennas are in the same plane, but w.r.t. to each
  other 120 degrees turned?
or
  are the other two main mission antennas 120 degrees tilted w.r.t.
  the satellite-nadir line? Most pictures of Iridiums suggest this.
