W4WFB,
I have two antennas supported by one tree each. On one I use a 1 gallon
chlorox bottle which I fill with water to get the desired weight and a
large pulley. The pulley is supported by another rope going around a
limb. However, I noticed that the weight did not respond fast enough to
relieve the strain imposed by the tree swaying, and it broke a #22 wire. I
replaced the wire with a #14 insulated wire and installed rubber tie down
straps about 3' long with steel hooks at the fixed end of the antenna. I
used 4 of them in parallel. On the other tree the antenna was longer, 90'
and the weight on the antenna, #14 insulated stranded antenna wire helped
some, so I just used the tie down straps and no weight. It was a bigger
tree and didn't sway as much in the wind. Both been up for over three
years. You have to replace the rubber tie down straps periodically.

I am using a Carolina Windom 80 suspended with 3/16" nylon rope through
stainless steel eyehooks up 50' between two large oak trees. These trees are
approx 123 feet apart. Because I am located in hurricane alley and
subject to high
winds, I would like to remove the permanent tiedown on one of the trees and
tie a weight to the rope. I would like to know how much weight should be
used.
What kind of weight (how many bricks or what-have-you). Thanks. Roy
