My G5RV is up in the oak trees here and is attached using springs at each
end. They are about 12 inches long and 1 inch in diameter. Been up for a
couple of years with no problems.

The ARRL Antenna Book suggests using a pulley and counter weight to allow for
the varying distances between trees caused by wind. At my former QTH, Ellijay
GA, I noticed that in very gusty conditions sometimes the support trees moved
in opposite directions at the same time. I decided to make my
This is Alan's site (as is the previous posting). I whole heartedly recommend
the CSV-19. It is simple to use and effective, particularly if you have tall
trees.
I've tried most of the other suggested methods, and while most will work to
some degree or another, they usually take multiple tries

A few years ago I used a catapult and a drilled golf ball with some braided
nylon line over an oak tree. When it became stuck in a branch, I wound the line
round a piece of wood and gave it my full weight to release it. The end result?
I literally shot myself in the foot, brea
I've gotten my fair share of storms here too and rather than go the
route of counter weights since I had to kinda skirt the side of a big
cedar I opted for a rope method.
I ended up tying two ropes together at the center point of the dipole.
Then ran the rope up into the trees. The rope bears all

it uses the arms, legs and back and is directly in line with your spine.

It works if you delete the "/csv19/index.htm" part.

Dan's comment is very true of *any* antenna, and most especially tree
mounted antennas.
To survive storms at all, it's very important that the antenna wire or
the halyards *never* fall under strain from the tree as it moves in the
wind. Even small trees can exert tons of pressure on the wire or
ntenna launching in the winter when foilage is less, but
the things come down whenever they please. With a loop over each "good"
branch, I can pull up new rope/wire even in the middle of summer.

What you need are a set of climbing poles, which needs the poles, 3 ropes and
a weight. The climbing poles are very two long rods with a hook on the end
of each able to slide along each other (but not tilt !). The poles extend
via two ropes, one per pole attached to the base of that pole and to ne

Don't be afraid of the self-appointed "list cops". There's only one
