... This also works. As the tree sways back and forth, you don't want the wire to keep moving. I brought the fixed end of the rope some distance from the tree, and fastened it to half of a cinder block laying on the ground. The cinder block will move to give you slack, but not move back when the branch moves in the other direction. Tam/WB2TT Think FUSE. Choose your point of failure, don't let it happen. 73's Richard Clark, KB7QHC A couple of decades ago, I experimented with the "cylinder" (don't know the correct term for it) from a screen door. This is the device which allows the door to be opened quickly and then to close slowly. There is an adjustment on it which allows this action to be speeded/slowed. I remember that I ended up with 3 or four in series. The final "fail safe" was a weight which would move to prevent damage to the antenna. It worked until I went on to other antennas ... I am surprised no antenna manufacturer has designed a device more suitable but along the same lines. Regards, JS |

I haven't had any problems using a weight, through a pulley, to hold a
wire antenna up. If that weight really gets to bouncing on the end of that line, I figure it isn't quite heavy enough, or the tree is moving so much the antenna isn't gonna stay up anyway (just hope the tree does). - 'Doc |
