It's typically not about the dead weight of the mast & antennas, it's about
reducing the bending moment on the mast under wind loading.

Subject: [TowerTalk] Thrust Bearing Installation
Installing a thrust bearing in a tower - Dead weight (along the gravity
vector) all on the rotator or all on the thrust bearing? Seeing such things
as sleeves for towers, I would surmise that all of the dead weight is on the
rotator and only off-axis loads (perpendicular to the gravity vector) are
handled by the thrust bearing. I use two thrust bearings in my tower which
I don't believe effects the answer to the above question. Ken K5RG
