[Boatanchors] Kinda off topic

[Bob]

glad you asked John. 
I moved recently and was watching my tall pine and oak trees sway in the 
breeze.....so it made me wonder what I was going to use to keep my 
antennas from snapping.   160 meter windom, inverted L, maybe even 
something bigger....  don't know... have two acres to play with now...

Anyway, I figured I'd come up with a way...however, now I don't have to 
do much thinking about it.  Lots of ideas came through.  

Have a good weekend all.
Bob W5UQ,
now, north of Houston near Magnolia, Texas.

I have the full wave loop strung between two large Oak trees. It is a vertical loop so don't be concerned with four ropes since the top strand of wire is the main support for the loop. The wire is #12 enameled copper so it is NOT steel but will handle the stress .

The the antenna is attached to the pulley via Dacron rope from the insulator and over to the pulley and through the pulley and on down to the ground. In order for the rope to move up and down through the pulleys, the down rope from the pulley will NOT be tied off in a fixed arrangement, but will have weights on their ends suspended above the ground to allow the weights to move up and down providing slack for the antenna as the tree sways and yet offer the antenna protection from breakage by the swaying of the trees.
