Tough one. unbalanced antennas like that are very hard to handle. If you
can get a pulley on the mast above it you can run a lifting line out as far
as you can reach on the heavy side to help take the strain off. You can
also push a tag line out the light end of the boom as far as possible to
have someone on the ground act as a counterweight. On some antennas when
you do this you can then loosen the boom clamps and slide the boom sideways
to get closer to balance in the middle.
