My Sky installation is wobbly at the top, and I have questions about installing guy wires.
The Sky sits atop a 10-foot schedule 80 PVC pipe attached to my children’s largely unused playset. The first two feet of the pipe are held with 3 brackets to one of the 2x4’s which once supported the playset’s canvas roof. The remaining 8 feet are unsupported, and it visibly tilts even with a light wind. I filled the pipe with sand before I mounted it, expecting that to provide more stability than it did; I suspect it’s top heavy from the Sky and its 8 batteries.
I’m considering a 3-ring guy wire mast clamp (https://www.summitsource.com/Channel-Master-CM-9015-Adjustable-Triple-Ring-Guy-Wire-Mast-Clamp-up-to-2-inch-Mast-3-Way-Antenna-Mount-Fastener-Mast-Support-HDTV-P8745.aspx).
Will the clamp and metal guy wires create any significant risk of becoming a lightning rod? About 18 feet off the ground, the Sky is the tallest object in our yard (we’re in a 10-year-old neighborhood of single-story homes with few trees, all young).
Can I use a non-metallic material, such as nylon string, for the guy wire? Is there a non-conductive material that is weather-resistant and doesn’t stretch out over time?
Finally, instead of using a turnbuckle with rings (eyes) at each end, can I use hook-and-eye turnbuckles and hook them directly into the screw eye at the base of each guy wire, or is this not recommended?
I appreciate the feedback. I’m really out of my element here
