The tram system is quite simple, as long as you have
two people supporting the ends of the big yagi!
Balance makes perfect. Use a rope loop on each end of
the beam, this way it's easy to rid the rope when
needed. Attach
a strong tram line above your intended point.
If it's a heavy beam then block and tackle to make the
pull easier. 4 or more people with "ONE" commander are
needed to get it up there!!!!
