- I'm late to this thread, although I've been watching it spiral around for some time, I've been too busy to respond. Used to be horizontal tower motion, I think. We finally reached the point where I'm

- You need to know which type of pine tree you are working with, some are very sturdy and some very weak. Ask a local who is familiar with the trees in your area which are the most and least sturdy. Th

- My tree is a Douglas Fir (Pseudotsuga menziesii), which is quite different from a pine tree. Doug Fir is the strongest North American softwood species. Based on 23 years experience with antennas in i

- No kidding! I just looked it up on Matweb.com and the flexural yield strength is listed at 8100psi! The elastic modulus is about a thirtieth that of steel (1000ksi vs. 30,000ksi) , but the cross sec

- Exactly! The tree is much stronger and more flexible than a steel tower. I can't begin to estimate the wind load that the branches present, but it is probably measured in 100's of sq. ft. 73, Clay W

- Now I understand why The Gravity Group, CCI, and other companies who build wooden roller-coasters charge a much higher price when they use Douglas Fir. If they spend the (lots of) extra money up fron

- I wouldn't even consider attaching a tower to a tree, or mounting antennas (except maybe wires) on one. I'm surrounded by pine trees, and the tops appear to sway a few feet during high winds. If it w
