Hello all, The south end of my 80-meter dipole runs among trees. The trees are higher than the antenna wire and have limbs which are above the dipole. Big limbs. The dipole is made of #14AWG THHN. It

I made sure the dacron rope I use to hold my dipole up had a significantly lower break strength than the wireman wire I used for the dipole itself. It's still not a guarantee, as the branch may kink

Hi Steve, How did you get ropes to support that wire up there? I'm guessing it wasn't easy. Rather than a mechanical fuse, most of us use strain relief in the form of a pulley and weight on one end.

I use sash weights from old windows at one end of my wire antennas. Up and down with tree sway and wind load. Don W7WLL Hello all, The south end of my 80-meter dipole runs among trees. The trees are

What is your concern? I use the same wire for temporary Beverage antennas and twice in the last 10 years I had tree branches fall and break the wire. It is easy to splice the THHN back together. John

Hi John, In my initial posting I forgot to mention the reason for my concern. The north leg of the dipole is supported on the west end of my house at two points. A tree limb falling on the south leg
