You can bend your dipole or random wire in any shape that you have to and it
will still work.

If you've got 50ft high trees, then I'd use them as much as possible. A 'wrist
rocket', fishing pole, and bolt/nut combo works great for stringing wires up
to 70' high (use fishing line to pull up a nylon cord, which is used to pull up
rope).
