[TowerTalk] Weight on ends of a OCF diploe

[Christopher Brown]

Only works if sway is fairly limited.  Flexible trees combined with
winter winds that will be 30 - 60 mph constant with 5 - 30 second
"bursts" of up to 120mph...  When they are directly along the line of
the antenna can be an issue unless you have a bungie that can extend > 10ft.

>> I saw an amazing thing once.  The South Dakota breeze caused my weight to head upward with some momentum.  The antenna then went slack while the weight was still moving upward. The wind caught the antenna tightening it while the weight was headed back down literally causing a snapping sound when the weight bounced. I'm sure it applied a great deal more instantaneous force than the weight alone. The next morning the weight and antenna were on the ground.

>> Chuck,  This is a situation where whatever you have is probably a good starting point.  Ham's are known for collecting junk and one can get quite artistic cleaning out ones garage.  I use old style window weights but if the XYL will let me get away with it, I might find an old radio chassis that might do well also.  Only a ham would think that to be artistic.......
