The short answer: 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.
What should I decide before buying?
- Choose it for the CFM-34 or CFM-34HD path described by the UGS and mast guides.
- 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.
What must match during setup?
- The clamp is documented with CFM-34, CFM-34HD, and the UGS guy-line system.
- Its physical diameter range does not approve every mast material or load.
- The antenna-specific height and guying restrictions still control.
- Do not substitute generic clamps or fasteners.
What deserves a stop and recheck?
- 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.
How should I put it away?
- 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.
