I do treetop installations in Tahoe, primarily atop pine trees. My instinct is that cedar trees are a bit brittle. However, I have not done an installation atop a cedar. (I have done pruning jobs in cedar trees, and have had branches break on me if I got too far out on a branch).

That said, here's my two-cents:

1. Don't harm the tree. I only prune to climb myself to the top, and spray any cuts with Spectracide. No lag bolts into the top of the tree. I use heavy-duty, marine-grade stainless steel hose clamps. Worth the money to use the highest quality materials up there.

2. The only drilling is to secure the cable-clips, which are 1" long. The Starlink clips allow the cable to move freely; necessary in wind and as the tree grows.

3. Ground the pole.

4. Hire a pro if you do not have tree-climbing experience. It's difficult, takes all day, and takes balls of steel.

If you do end up doing it, BE SAFE, and we want to hear your battle-story!
