Paul, as Vin suggests I also use a system of marine pulleys to avoid
problems when the trees sway. I would like to add that because most trees
tend to grow over any object such as a rope that is hanging over a limb, it
is worthwhile to loosen up occasionally the ropes that go over the trees to
the pulleys, say once every 9 - 12 months. This will prevent the ropes
becoming stuck.
For wire I use plastic covered Flexweave approximately #12 for reasons of
strength and ease of handling, plastic covered because the many local birds
perch on the antennas.

One more thing I might add is that in case you had not planned on doing
this, use a system of pulleys (I use marine pulleys) so that as the trees
(I assume you are erecting the antenna between trees) sway, the antennas
will give. If you need more info on this, contact me off list. I will be
happy to send you a graphic of how I do this.
