    Maybe we're not talking about the same thing. A tramline (typically steel 
cable) is a line where the load is under the line and suspended by a pulley 
whereas the antenna sits on top of a trolley line and the antenna is slid up 
the line (typically ropes). The tram system is MUCH easier to rig and use 
than a trolley set-up.

    Sure, that's a wash but on the tower you don't have to rig the haul line, 
tramline, comealong, etc.

    Well, THAT'S true.

    Repairing it on the tower will take one guy about 30-60 minutes. Rigging 
up the tramline, repairing the antenna on the ground and re-installing it 
will take your 3-man crew and 60-90 minutes. Splitting hairs (hares?) but I 
prefer to do things the quickest  and easiest way I can.
