Hi, Pretty sure I'll probably be able to come up with something that will more or less work, but was wondering if any of you folks have a real clever solution for this: Will be stringing a horiz wire listening only antenna between two trees out back. Trees have a fair amount of movement, particularly in the winter. So, I thought I'd fasten one end securely, and then use the pulley arrangement, with a hanging weight, like you see in all the pix for this sort of thing. But, we get a lot of ice and freezing rain, and I doubt that the pulley would really function well, if at all in the winter. But, perhaps ? Think a large metal ring, with a Dacron rope goint thru (one end to the wire end) would be better ? Coat Dacron with Silicone Spray ? In Colorado I had a 150' balanced fed dipole hung between a blue spruce and an oak tree, the spruce end fastened and the oak end with a pulley held up with a garage door spring to the oak, a rope through the pulley to the ground and tied off to a screw eye in the trunk of the tree. I used nylon ropes, allowed the dipole to sag a couple feet and never had a problem with it. The garage door spring was about 4 feet long relaxed and I could stretch it a foot or so just pulling on it, it was stretched maybe two feet with the antenna up. The pulley was handy because the feed line broke off and I was able to lower the feed point to the ground and make repairs. The antenna would bounce around on windy days, stayed up with about an inch coating of snow and ice and got me a QSL card from a Clipperton Island expedition. W8LNA |
