Mechanical safety comes before SWR:
CHA HD GUY CLAMP is the two-piece mast ring used to connect the UGS three-line system to larger CFM masts. It creates a deliberate guy point without drilling or improvising attachments on the carbon-fiber tube.
Stop-work conditions
- Never install it on a cracked, deformed, or wrong-diameter section.
- Do not overtighten into carbon fiber.
- Keep hands clear while a loaded mast moves.
- Lower the mast immediately if the clamp rotates, slips, or separates.
Control wind, leverage, and movement
- Confirm the selected mast section is the documented 24-26 mm diameter at the correct guying height.
- Use all supplied stainless hardware and three carabiners.
- Do not treat the clamp as a lifting point, antenna bracket, or reason to exceed the mast rating.
Recover without creating the next failure
- Inspect both halves, fasteners, guy holes, and carabiners.
- Remove grit before clamping to a mast.
- Store the matched hardware together.
- Replace any bent, cracked, corroded, or missing component.
Guying can stabilize a documented installation, but it does not increase the published load or make an unapproved support chain safe.
Use the current CHA HD GUY CLAMP instructions.
