[TowerTalk] Raising a TH-11 DX antenna

[Michael Walker]

Not the same.

The TH11 will likely be 6" above the thrust bearing.  The tram line is at
the top of the mast maybe 6ft away.

This is why you need a pulley on the line on the mast and that the
rope/tram line is not fixed to the mast.  The only load on the mast done
this way is vertical.

This is critical.
