That support rope Jim referenced has done a great job here for a number of
years supporting wire antennas over 100 feet long hung in tall fir trees. I
did provide strain relief - a pulley at one end attached to a weight so the
tree can move freely. We do get winds gusting over 60 mph here most winters
and the rope has handled the shock load of the tree whipping and jerking on
a 20 lb weight. 

The wire I use is hard drawn stranded copper.  I purchased mine through Ham
Radio Outlet back when I lived near one of their stores. It is also on line

Pulleys yes. Cord at a marine store will be expensive.  Here's a link to the
company that makes great antenna rope that is resold by several large ham
vendors. 3/16-in is enough for strength, but 5/16-in is easier to grip if
you need to pull it to put a lot of tension on it.
