Last weekend I went monkey and climbed the redwood tree. I got as high as I could, and screwed three eye-bolts into the trunk with marine-grade pulleys on them, then ran some dacron cord through the pulleys and heaved heavy objects attached to the lines away from the tree at right angles. The idea is to be able to use one of the lines as a transit line to haul up an inverted-V feedpoint, and for the other two to be the supports for 80 and 160 inverted L antennas.
As it turns out, I climbed up 58 feet before I chickened out. That's not quite the 1/2 wavelenength on 40 meters I was hoping for, but it's close enough. And I think whatever is up there will work a lot better than the G5RVjr at 22 ft.
